Dropper Type - Application Note
sHeat Radiation and Reliability
The reliability of an IC is highly dependent on its operating temperature. Design should pay particular attention to ensuring ample space for radiating heat. Be sure to apply silicon grease to the IC before attaching a heatsink, and to secure it firmly to the heatsink. Other important items to be considered regarding heat radiation include air convection during operation.

0.588 to 0.686[N*m] (6.0 to 7.0[kgf*cm])
sCalculating Internal Power Dissipation (PD)
PD is given by the following formula: PD=IO*[VIN(mean)-VO] Determine the size of the heatsink according to the relationship between allowable power dissipation and ambient temperature.
0.686 to 0.882[N*m] (7.0 to 9.0[kgf*cm])
0.588 to 0.784[N*m] (6.0 to 8.0[kgf*cm])

sRecommended Silicone Grease
qG746 SHINETSU CHEMICAL INDUSTRIES CO., LTD. qYG6260 TOSHIBA SILICONE CO., LTD. qSC102 DOW CORNING TORAY SILICONE CO., LTD. Please select a silicone grease carefully since the oil in some grease can penetrate the product, which will result in an extremely short product life.
VIN (mean)
VIN (max.)
VIN (min.)
sOthers
When setting the DC input voltage, pay attention to the following: qVIN(min) must be no less than the sum of output voltage and the minimum voltage difference between the input and output. qVIN(max) must be no more than the maximum rated DC input voltage. * Devices can not be operated in parallel to increase current. * An isolation type diode is provided from input to ground and also from output to ground. These may be destroyed if the device is reverse biased. In this case, use a diode with low VF to protect them.
sHeatsink Design
The maximum junction temperature Tj(max) given in the absolute maximum ratings is specific to each product type and must be strictly observed. Thus, thermal design must consider the conditions of use which affect the maximum power dissipation PD(max) and the maximum ambient temperature Ta(max). To simplify thermal design, the relationship between these two parameters has been presented in a graph, the Ta-PD characteristic graph. Thermal design should include these steps: 1. Obtain the maximum ambient temperature Ta(max). 2. Obtain the maximum power dissipation PD(max). 3. Look for the intersection point on the Ta-PD characteristic graph and determine the size of the heatsink. The size of the heatsink has now been obtained. However, in actual applications, a 10 to 20% derating factor is introduced. Moreover, the heat dissipation capacity of a heatsink highly depends on how it is mounted. Thus, it is recommended to measure the heatsink and case temperature in the actual operating environment. The Ta-PD characteristics for each product type are provided for reference purposes.
sRectifier Diodes for Power Supplies
To rectify the AC input using rectifier diodes in power supplies, use any of the SANKEN rectifier diodes shown in the following list. (Use axial type diodes in a center-tap or bridge configuration.)

The output voltage may be increased by inserting resistor REX between terminals No.4 (sensing terminal) and No.3 (output terminal). The current IREX flowing into terminal No.4 is 1mA (typ.), therefore the adjusted output voltage VOUT is: VO=V04+IREX*REX *V04: output voltage of SI-3000F series However, the built-in resistor (between terminals No. 4 and No.1) is a semiconductor resistor, which has approximately thermal characteristics of +0.2%/C.

The output voltage may be increased by inserting resistors REX1 between terminals No.4 (sensing terminal) and No.3 (output terminal) and REX2 between terminals No.4 and No.1 (ground terminal). The current I4IN flowing into terminal No.4 is 1mA (typ.) so the thermal characteristics may be improved compared to the method shown in 1 by setting the external current IREX1 at approximately 5 times the value of I4IN (stability coefficient S=5). The adjusted output voltage VOUT in this case is: VO=V04+REX1*IREX1 IREX1=S*I4IN The value of the external resistors may be obtained as follows: VO-V04 V04 REX1= REX2= S*I4IN , (S-1)*I4IN

The output voltage may be increased by inserting resistor REX between terminals No.4 (sensing terminal) and No.3 (output terminal). The current IREX flowing into terminal No.4 is 1mA (typ.), therefore the adjusted output voltage VOUT is: VO=V04+IREX*REX *V04: output voltage of SI-3000J series However, the built-in resistor (between terminals No. 4 and No.1) is a semiconductor resistor, which has approximately thermal characteristics of +0.2%/C.

The output voltage may be increased by inserting resistors REX1 between terminals No.4 (sensing terminal) and No.3 (output terminal) and REX2 between terminals No.4 and No.1 (ground terminal). The current I4IN flowing into terminal No.4 is 1mA (typ.) so the thermal characteristics may be improved compared to the method shown in 1 by setting the external current IREX1 at approximately 5 times the value of I4IN (stability coefficient S=5). The adjusted output voltage VOUT in this case is: VO=V04+REX1*IREX1 IREX1=S*I4IN The value of the external resistors may be obtained as follows: VO-V04 V04 REX1= REX2= S*I4IN , (S-1)*I4IN

Switching Type - Application Note
sHeat Radiation and Reliability
The reliability of an IC is highly dependent on its operating temperature. Design should pay particular attention to ensuring ample space for radiating heat. Be sure to apply silicon grease to the IC before attaching a heatsink, and to secure it firmly to the heatsink. Other important items to be considered regarding heat radiation include air convection during operation. The reliability of peripheral components such as capacitors and coils is closely related to temperature. A high operating temperature may reduce the service life. Exceeding the allowable temperature may burn the coils or damage capacitors. It is important to make sure that the temperature of output smoothing coils and input/output capacitors do not exceed their allowable levels during operation. Allow for variation in the ratings of the coils and minimize heat emission as far as possible. (For peripheral components, refer to the user manuals.)

sOthers
* Parallel operation can not be performed for increasing current. * This type IC regulators can not be used for boosting current and raising voltage.
sRectifier Diodes for Power Supplies
To rectify the AC input using rectifier diodes in power supplies, use any of the SANKEN rectifier diodes shown in the following list. (Use axial type diodes in a center-tap or bridge configuration.)
sHeatsink Design
The maximum junction temperature Tj(max) given in the absolute maximum ratings is specific to each product type and must be strictly observed. Thus, thermal design must consider the conditions of use which affect the maximum power dissipation PD(max) and the maximum ambient temperature Ta(max). To simplify thermal design, the relationship between these two parameters has been presented in a graph, the Ta-PD characteristic graph. Thermal design should include these steps: 1. Obtain the maximum ambient temperature Ta(max). 2. Obtain the maximum power dissipation PD(max). 3. Look for the intersection point on the Ta-PD characteristic graph and determine the size of the heatsink. The size of the heatsink has now been obtained. However, in actual applications, a 10 to 20% derating factor is introduced. Moreover, the heat dissipation capacity of a heatsink highly depends on how it is mounted. Thus, it is recommended to measure the heatsink and case temperature in the actual operating environment. The Ta-PD characteristics for each product type are provided for reference purposes.

sSelecting External Components
1. Inductor L1 1) It must be suited for switching regulators. Do not use inductors as noise filters as they generate excessive heat. 2) It must have the appropriate inductance value. If the inductance is too small (150H or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection circuit within the rated current range. 3) The rated current must be satisfied. If the rated current is exceeded, magnetic saturation leads to overcurrent. 2. Capacitors C1 and C2 1) They must satisfy the withstand voltage and allowable ripple current. Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal oscillation of the IC. 2) C2 must be a low-impedance type capacitor. A low-impedance type capacitor is recommended for C2 to ensure minimum ripple voltage and stable switching operation. 3. Diode D1 The Sanken SFPB54 diode is recommended for D1. If you intended to use an equivalent diode, be sure to use a Schottky Barrier diode and make sure that the reverse voltage applied to terminal 2 of the IC does not exceed the value (-1V) given in the absolute maximum ratings. If you use a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may damage the IC.

Caution
1. Selecting External Components (1) Choke coil L1 To maintain the stable operation of the regulator, choke coil L1 should be selected appropriately. When selecting choke coil L1, consider the following: a) Suitable for a switching regulator Do not use a coil as a noise filter because it generates excess heat. b) Appropriate inductance The greater the inductance of the choke coil, the smaller the output ripple voltage. However, the size of the coil increases large as the inductance increases. If the inductance is low, a greater peak current flows to the IC and loss increases. This is not favorable for stable operation. The standard external circuit shows reference inductance values suitable for stable operation. However, the appropriate inductance may also be calculated as follows: (VIN-VO)*VO L= IL*VIN*f Where, deltaIL indicates the ripple current of the choke coil that is roughly set as follows: * If the working output current is close to the maximum rating (3 A) of SI-8000S Ripple current = output current x 0.2 to 0.3 * If the working output current is about 1.0A or less Ripple current = output current x 0.3 to 0.4 c) Satisfying the rated current The rated current of a choke coil must be greater than the maximum load current. Note that the inductance decreases drastically and an excess current flows if the load current exceeds the rated current of the coil. d) Good DC current superposition characteristics The current flowing through a choke coil is a triangular waveform current superimposed on a DC current equal to the load current. The coil inductance decreases as the load current increases. In general, the coil can be used until the inductance drops to 50% of the rated value. Use this as the reference value for selection.
(2) Input capacitor C1 Input capacitor C1 operates as a bypass capacitor in the input circuit. When selecting input capacitor C1, consider the following: a) The breakdown voltage is higher than the maximum input voltage. b) Satisfies the allowable ripple current Exceeding the ratings of this capacitor or using it without derating may reduce its service life and also cause the regulator to malfunction. Therefore, an input capacitor with a sufficient margin should be selected. With the SI-8000S Series, the effective ripple current Irms flowing to the input capacitor can be calculated approximately as follows: VO x IO Irms 1.2 x VIN (3) Output capacitor C2 Output capacitor C2 operates as a smoothing capacitor for switching output. The output ripple voltage from the regulator is determined by the product of the pulsating current part IL (=C2 chargedischarge current) of the choke coil current and the equivalent series resistance ESR of the output capacitor C2. Vrip=IL*C2ESR Therefore, a capacitor of low equivalent series resistance ESR should be selected to reduce the output ripple voltage. It is recommended to select a low-impedance capacitor intended for use with switching regulators as C2. (4) Diode D1 Use a Schottky barrier diode for D1. If you use a general rectifier diode or fast recovery diode, the IC may be damaged. (Sanken RK46 recommended) 2. Notes on Pattern Design (1) Large current line Since a large current flows through the bold lines in the standard external circuit make the pattern as wide and as short as possible.

(2) Input capacitor Place the input capacitor C1 and output capacitor C2 as close to the IC as possible. Since a large current flows through the lead wires of the input and output capacitors to charge and discharge them quickly, minimize the lead wire length. The pattern around the capacitors should also be minimized.

e) Less noise A drum-type open magnetic core coil can affect peripheral circuits with noise because the flux passes outside the coil. To avoid this problem, use a toroidal, EI, or EE type open magnetic core coil.

(3) Sensing terminal Output voltage sensing terminal VOS should be connected as close to output capacitor C2 as possible. If the terminal is far from the capacitor, the decreasing regulation and increasing switching ripple may result in abnormal oscillation. Example of basic pattern
SI-8000S
3. Variable Output Voltage The output voltage can be increased by connecting a resistor to VOS terminal No. 4. (There is no way of decreasing the voltage) (1) Variable output voltage with single external resistor

The output voltage adjustment resistance REX is calculated as follows: VO'-VS REX= IVS VS : Set output voltage of product VO' : Adjusted output voltage IVS : Inflow current to Vs terminal * The temperature characteristics of output voltage worsen because the value REX is not compensated for temperature. The Vs value fluctuates by up to 20% depending on the IC product. Since the output voltage fluctuates more, a semi-fixed resistor is necessary for accurate output voltage adjustment. If Vs and REX are constant, the range of output voltage fluctuation can be expressed as follows: VO'-VS VO' VO':Adjusted output voltage VO'(%)=20* (2) Variable output voltage with two external resistors
Applications
1. Soft Start Connecting a capacitor to terminal no. 5 permits a soft start at poweron. Delay time Td and rise time Ts can roughly be calculated as shown below. (However, the values may slightly vary in an actual application.) If the capacitance of C3 is increased, it takes longer to discharge C3 after VIN is turned off. Therefore, it is recommended to set the value within 10F. When not using the soft start function, keep terminal no. 5 open. 0.7xC3 Td= (sec) 20x10-6 4.845xC3 Ts= (sec) VINx20x10-6

2. Output ON/OFF control Output can be turned on and off by using the soft start terminals. Set the soft start terminal voltage to VSSL (0.2V typ.) or less to stop output. To switch the potential at the soft start terminals, drive the open collector of the transistor. Since the discharge current from C3 flows to the ON/OFF control transistor, limit the current for protection. The SS terminal is pulled up to the power supply in the IC and no external voltage can be applied.

The output voltage adjustment resistances REX1 and REX2 are calculated as follows: VO'-VS REX1= S*IVS VS REX2= (S-1)*IVS S:Stability factor Bypassing the current to REX2 improves the temperature characteristics and voltage fluctuation ranges more than the method of (1). Stability factor S indicates the ratio of REX1 to Vs terminal inflow current. Increasing the S value improves the fluctuations of the temperature characteristics and output voltage. (Usually 5 to 10) If the Vs and REX values are constant, the output voltage fluctuation range can be calculated as follows: 20 VO'-VS VO'(%)= * S VO'

sNotes of Pattern Design
1) Thick lines in the Standard External Circuit are lines through which a large current flows. Make these pattern lines as thick as possible. 2) Place capacitor C1 on the input side as closely as possible to terminals no.2 and no.4 of the STR7000/7100 series. C1 may be used in combination with a smoothing capacitor for rectifying, but the above points must be taken into consideration. In cases where C1 is not provided or it is placed too far from the terminals stated above, abnormal oscillation due to poorer transient response or increased ringing may occur. 3) Connect voltage sensing terminal VO.S and GND as closely as possible to output capacitor C4 (a current of approximately 1mA flows into the VO.S terminal). If they are placed too far from C4, abnormal oscillation due to decreased regulation or increased switching ripple may occur. 4) Connect current sensing terminal C.S and GND as closely as possible to the detection resistor Rs (a current of approximately 0.5mA flows from the CS terminal). If they are placed too far from Rs, a decrease of the overcurrent setting point due to the voltage drop in the pattern, or malfunction of the protection circuit due to increased ringing may occur.

sCaution
1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the IC as possible in order to assure low ripple voltage and stable switching operation. 2. The SI-8200L and 8300L series do not have a built-in overcurrent protection circuit. Thus, avoid short-circuit conditions that may cause an overcurrent. 3. The SI-8300L series may not start up if the input voltage rises too rapidly. Do not use the SI-8300L series in applications where the input terminal, pin6, is opened and closed directly in a state where the input voltage is already applied. 4. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits. 5. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit. 6. Since the SI-8200L and 8300L series have an open-package construction, they can only be used in specific environments. Verify the operating environment and use the IC within the conditions indicated in the reliability data.

sSI-8500L application circuit
Terminal no.2 is for soft start. Connecting a capacitor to the terminal enables the soft start function. See page 85 for the formulas to calculate delay time and rise time. Output can be turned on and off by using the soft start terminal. To stop output, set the soft start terminal voltage to VSSL (0.2V typ.) or less. To switch the potential of the soft start terminal, drive the open collector of the transistor. Since the discharge current from C3 flows to the ON/OFF control transistor, limit the current for protection. The SS terminal is pulled up to the power supply in the IC and no external voltage can be applied.

1. Allocation of Components For the best operating environment, the ground should be a single ground line at the GND terminal (terminal 2 on the SI-8400L, terminal 3 on the SI-8500L), and the wiring from C1 and C2 to ground should be as short as possible. 2. Capacitors C1 and C2 1) They must satisfy the breakdown voltage and allowable ripple current. Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal oscillation of the IC. 2) C2 must be a low-impedance type capacitor to ensure minimum ripple voltage and stable switching operation. 3) C3 (SI-8500L only) is a capacitor for soft start. When not using soft start, leave terminal 2 open. It is pulled up inside the IC. 3. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits. 4. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit. 5. Since the SI-8400L and 8500L series have an open-package construction, they can only be operated in specific environments. Verify the operating environment and use the conditions indicated in the reliability data.

sCaution
1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the IC as possible in order to assure low ripple voltage and stable switching operation. 2. The SI-881L/8911L series does not have a built-in overcurrent protection circuit on terminal VO2(-5V). Thus, avoid short-circuit conditions that may cause an overcurrent. 3. Do not connect VIN(-) of SI-8811L to GND. The overcurrent protection circuit may not work if they are connected. 4. Terminals left unconnected in the connection diagram must not be connected to other circuits. 5. The IC's metallic heatsink is electrically floating. Do not connect it to GND or any other circuit. 6. Since the SI-8800L and 8900L series have an open-package construction, they can be operated in specific environments. Verify the operating environment and use the IC within the conditions indicated in the reliability data.

Multi-Output Type - Application Note
sHeat Radiation and Reliability
The reliability of an IC is highly dependent on its operating temperature. Design should pay particular attention to ensuring ample space for radiating heat. Be sure to apply silicon grease to the IC before attaching a heatsink, and to secure it firmly to the heatsink. Other important items to be considered regarding heat radiation include air convection during operation. The reliability of peripheral components such as capacitors and coils is closely related to temperature. A high operating temperature may reduce the service life. Exceeding the allowable temperature may burn the coils or damage capacitors. It is important to make sure that the temperature of output smoothing coils and input/output capacitors do not exceed their allowable levels during operation. Allow for variation in the ratings of the coils and minimize heat emission as far as possible. (For peripheral components, refer to the user manuals.)
sFastening Torque
STA800M Series (when using a spring) 0.588 to 0.784 [N*m](6.0 to 8.0[kgf*cm] SLA3000M Series 0.588 to 0.784 [N*m](6.0 to 8.0[kgf*cm]
sRecommended Silicon Grease
qG746 SHINETSU CHEMICAL INDUSTRIES CO., LTD. qYG6260 TOSHIBA SILICONE CO., LTD. qSC102 DOW CORNING TORAY SILICONE CO., LTD. Please select a silicone grease carefully since the oil in some grease can penetrate the product, which will result in an extremely short product life.
sHeatsink Design
The maximum junction temperature Tj(max) given in the absolute maximum ratings is specific to each product type and must be strictly observed. Thus, thermal design must consider the conditions of use which affect the maximum power dissipation PD(max) and the maximum ambient temperature Ta(max). To simplify thermal design, the relationship between these two parameters has been presented in a graph, the Ta-PD characteristic graph. Thermal design should include these steps: 1. Obtain the maximum ambient temperature Ta(max). 2. Obtain the maximum power dissipation PD(max). 3. OLook for the intersection point on the Ta-PD characteristic graph and determine the size of the heatsink. The size of the heatsink has now been obtained. However, in actual applications, a 10 to 20% derating factor is introduced. Moreover, the heat dissipation capacity of a heatsink highly depends on how it is mounted. Thus, it is recommended to measure the heatsink and case temperature in the actual operating environment. The Ta-PD characteristics for each product type are provided for reference purposes.

sSelecting External Components
1. Inductors L1 and L2 (1) Suitable for switching regulators Do not use a coil as a noise filter because it generates excess heat. (2) Appropriate inductance A low inductance may cause abnormal oscillation, or cause the overcurrent protection circuit to malfunction in the rated current range. (3) Satisfying the rated current Exceeding the rated current may generate an extremely high current to flow due to magnetic saturation. 2. Capacitors C1, C2, and C3 (1) Satisfy the breakdown voltage and allowable ripple current Exceeding the ratings of these capacitors or using them without derating may shorten their service lives and also cause abnormal oscillation. (2) Low impedance (C2, and C3) A low-impedance model is recommended for C2 and C3 to reduce the ripple voltage and stabilize switching. For stable operation throughout the input voltage range, however, the DC equivalent series resistance (ESR) of C2 and C3 should be 0.1 ohm or less. 3. Capacitors C4 and C5 (1) C4 and C5 are soft-start capacitors.
sSelecting Ch2 Output Voltage
When the VO2Cont terminal voltage is set to 0.5V or less, the output voltage changes to the values shown below. To switch the potential at the VO2Cont terminal, drive the open collector of the transistor. No external voltage can be applied to the terminal. Leave the terminal open when not in use because the terminal is already pulled up in the IC. When using terminal no. 9, short it to terminal no. 10. ( ): STA802M

sSoft Start ON/OFF Circuit
Terminal nos. 3 and 8 are soft start terminals. Connect a capacitor to the terminal to permit a soft start. Output can be turned on and off by using the soft start terminals. Set the soft start terminal voltage to VSSL (0.15V) or less to stop the output. To switch the potential at the soft start terminals, drive the open collector of the transistor. Since the discharge currents from C4 and C5 flow to the ON/OFF control transistor, limit the current for protection. The SS terminal is pulled up to the power supply in the IC and no external voltage can be applied to the terminal.

RFLG connected between FLG and VIN
*1 IS1 is specified at -5(%) drop point of output voltage VO on the condition that VIN = 7V, IO = 0.1A. *2 Output is ON even when output control terminal VC is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an LS-TTL circuit. *3 Total of four circuits *4 The FLG output latched by delay DLY after OCP detection. (SLA3005M shuts down the output voltage simultaneously at latching.) Set the VIN or VC to low to reset latching. Leave a time lag of Cd x 600s or more before restart.

: Input capacitor (Approx. 47F) This capacitor is required if the input line is inductive and in the case of long wiring. : Output capacitor (47 to 220F) : Delay setting capacitor (0.1F or more) Use Cd to set the delay time (tDLY) from when a low VO level due to OCP operation is detected until a flag signal is output. This prevents a rush current from causing malfunction. Approximate calculation: tDLY (Cd x VDLYth)/IDLY[sec] When using soft start on VIN or if CIN has a large capacitance, set tDLY long enough for the output voltage to rise sufficiently Be sure to connect Cd and do not use it for other applications, such as short circuiting Cd. : Reverse biasing protection diode This diode is required for protection against reverse biasing of the input and output. : Set this to limit the inflow current into the FLG terminal to 1mA or less.

sCalculating the internal dissipation
PD is calculated as follows: PD=[IO1*(VIN-VO1)]+[IO2*(VIN-VO2)]+[IO3*(VIN-VO3)]+[IO4*(VIN-VO4)]+VIN*IG
sEstimating Tj by heat measurement
1. Measuring position: At the root of pin 13 2. Add the thermal resistance "j-L" between the junction and pin 13 and the Pd product of each channel to the measured temperature. j-L is as follows : j-L1:8C/W, j-L2:7C/W, j-L3:5C/W, j-L4:8C/W The calculation formula is as follows :Tj=j-L1*Pd1+j-L2*Pd2+j-L3*Pd3+j-L4*Pd4+T13pin
