Current is measured at the input of the module. Figure 29: Input reflected-ripple test setup COPPER STRIP To maintain low noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. Figure 32 shows the input ripple voltage (mVp-p) for various output models using 200 F(2 x100uF) low ESR tantalum capacitor (KEMET p/n: T491D107M016AS, AVX p/n: TAJD107M106R, or equivalent) in parallel with 47 F ceramic capacitor (TDK p/n:C5750X7R1C476M or equivalent). Figure 33 shows much lower input voltage ripple when input capacitance is increased to 400 F (4 x 100 F) tantalum capacitors in parallel with 94 F (2 x 47 F) ceramic capacitor.

The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the module. An input capacitance must be placed close to the modules input pins to filter ripple current and ensure module stability in the presence of inductive traces that supply the input voltage to the module. FEATURES DESCRIPTIONS Remote On/Off The DNM/DNL series power modules have an On/Off pin for remote On/Off operation. Both positive and negative On/Off logic options are available in the DNM/DNL series power modules. For positive logic module, connect an open collector (NPN) transistor or open drain (N channel) MOSFET between the On/Off pin and the GND pin (see figure 34). Positive logic On/Off signal turns the module ON during the logic high and turns the module OFF during the logic low. When the positive On/Off function is not used, leave the pin floating or tie to Vin (module will be On). For negative logic module, the On/Off pin is pulled high with an external pull-up resistor (see figure 35). Negative logic On/Off signal turns the module OFF during logic high and turns the module ON during logic low. If the negative On/Off function is not used, leave the pin floating or tie to GND. (module will be On) Vin ION/OFF Safety Considerations For safety-agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 20A of glass type fast-acting fuse in the ungrounded lead. Vo On/Off Q1 RL GND Figure 34: Positive remote On/Off implementation Vin Vo Rpullup ION/OFF On/Off RL Q1 GND Figure 35: Negative remote On/Off implementation Over-Current Protection To provide protection in an output over load fault condition, the unit is equipped with internal over-current protection. When the over-current protection is triggered, the unit enters hiccup mode. The units operate normally once the fault condition is removed. DS_DNL04SIP16A_10052006 9 FEATURES DESCRIPTIONS (CON.) Over-Temperature Protection The over-temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the over-temperature threshold the module will shut down. The module will try to restart after shutdown. If the over-temperature condition still exists during restart, the module will shut down again. This restart trial will continue until the temperature is within specification Vtrim = 0.7 - 0.1698 x (Vo - 0.7525 ) For example, to program the output voltage of a DNL module to 3.3 Vdc, Vtrim is calculated as follows Vtrim = 0.7 - 0.1698 x (3.3 - 0.7525) = 0.267V Vo RLoad TRIM Rtrim GND Remote Sense The DNL provide Vo remote sensing to achieve proper regulation at the load points and reduce effects of distribution losses on output line. In the event of an open remote sense line, the module shall maintain local sense regulation through an internal resistor. The module shall correct for a total of 0.5V of loss. The remote sense line impedance shall be < 10.

By using a 1% tolerance trim resistor, set point tolerance of 2% can be achieved as specified in the electrical specification.

Without this external resistor, the output voltage of the module is 0.7525 Vdc. To calculate the value of the resistor Rtrim for a particular output voltage Vo, please use the following equation: 21070 Rtrim = - 5110 Vo - 0.7525 Table 2 Vo(V) 0.7525 1.2 1.5 1.8 2.5 3.3 Vtrim(V) Open 0.624 0.573 0.522 0.403 0.267 For example, to program the output voltage of the DNL module to 1.8Vdc, Rtrim is calculated as follows: 21070 Rtrim = - 5110 = 15K 1.8 - 0.7525 DNL can also be programmed by apply a voltage between the TRIM and GND pins (Figure 38). The following equation can be used to determine the value of Vtrim needed for a desired output voltage Vo: DS_DNL04SIP16A_10052006 10 FEATURE DESCRIPTIONS (CON.) The amount of power delivered by the module is the voltage at the output terminals multiplied by the output current. When using the trim feature, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module must not exceed the maximum rated power (Vo.set x Io.max P max). The DNL family has 3 different option codes for TRACK function. Option code A: the output voltage TRACK characteristic can be achieved when the output voltage of PS2 follows the output voltage of PS1 on a volt-to-volt basis. (Figure 41) Option code B: No TRACK function Option code C: Implementation of advanced power tracking techniques is based on connecting the power good signal or selecting proper value for external resistor R1 (Figure 40 to Figure 43). Voltage Margining Output voltage margining can be implemented in the DNL modules by connecting a resistor, R margin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to the output pin for margining-down. Figure 39 shows the circuit configuration for output voltage margining. If unused, leave the trim pin unconnected. A calculation tool is available from the evaluation procedure which computes the values of R margin-up and Rmargin-down for a specific output voltage and margin percentage. Vin Vo PS1 PS2 PS1 PS2 Rmargin-down Q1 On/Off Trim Figure 40: Sequential PS1 PS1 Rmargin-up Rtrim GND Q2 PS2 PS2 Figure 39: Circuit configuration for output voltage margining Voltage Tracking The DNM/DNL family was designed for applications that have output voltage tracking requirements during power-up and power-down. The devices have a TRACK pin to implement three types of tracking method: sequential, ratio-metric and simultaneous. TRACK simplifies the task of supply voltage tracking in a power system by enabling modules to track each other, or any external voltage, during power-up and power-down. By connecting multiple modules together, customers can get multiple modules to track their output voltages to the voltage applied on the TRACK pin. The DNL family has 3 different option codes for TRACK function: Figure 41: Simultaneous PS1 PS1 PS2 -V PS2 Figure 42: Ratio-metric PS1 PS1 +V PS2 PS2 DS_DNL04SIP16A_10052006 Figure 43: Ratio-metric 11 FEATURE DESCRIPTIONS (CON.) Sequential Sequential start-up (Figure 40) is implemented by connecting the power good pin of PS1 to the TRACK pin of PS2 with a resistor-capacitor (RC) circuit. Suggest to use 1F ceramic capacitor and 2K resistor here. Besides, this configuration requires PS1 to have a power good function. PS1 Vin Ratio-Metric Ratio-metric is implemented by selecting the resistor values of the voltage divider on the TRACK pin. To simplify the tracking design, set initial value of R2 equal to 20K at internal circuit and adjust resistor R1 for the different tracking method. The circuit diagram of Ratio-Metric is the same as Simultaneous when VoPS2 tracks the VoPS1. For Ratio-Metric applications that need the outputs of PS1 and PS2 go to the regulation set point at the same time (Figure 43), use the following equation (1) to calculate the value of resistor R1, set V=Voset,PS1-Voset,PS2 and V will be negative. R1 = [(Voset ,PS 2 + V ) - Vref ] * 20K --------------(1) Vref PS2 Vin VoPS1 PWRGD VoPS2 TRACK ENABLE R ENABLE C Simultaneous Simultaneous tracking (Figure 41) is implemented by using a voltage divider around the TRACK pin. The objective is to minimize the voltage difference between the power supply outputs during power up and down. For type A (DNX0A0XXXX A), the simultaneous tracking can be accomplished by connecting VoPS1 to the TRACK pin of PS2 where the voltage divider is inside the PS2. PS1 Vin Note: 1. Vref =0.4xVoset,PS2 2. V is the maximum difference of voltage between PS1 and PS2 supply voltage. For Ratio-Metric applications that need the PS2 supply voltage rises first at power up and falls second at power down (Figure 42), use the following equation (2) to calculate the value of resistor R1, set V0.4xVoset,PS2 and V will be negative. R1 = [(Vo set , ps 2 - V ) - Vref ] Vref * 20 K ------------------(2) PS2 Vin VoPS1 TRACK VoPS2 ENABLE ENABLE For type C (DNX0A0XXXX C), the simultaneous tracking can be accomplished by putting R1 equal to 30.1K through VoPS1 to the TRACK pin of PS2. PS1 Vin Note: 1. Vref =0.4xVoset,PS2 V is defined as the voltage difference between VoPS1 and VoPS2 when VoPS2 reaches its rated voltage.

To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. THERMAL CURVES Thermal Testing Setup Delta's DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted. The following figure shows the wind tunnel characterization setup. The power module is mounted on a test PWB and is vertically positioned within the wind tunnel. The height of this fan duct is constantly kept at 25.4mm (1'').
