XC6416 Series
Dual LDO Voltage Regulator with "GreenOperation"
JTR0333-006
GENERAL DESCRIPTION
GreenOperation Compatible
The XC6416 series is a high accurate, low noise, high ripple rejection, and low dropout CMOS Dual regulator with GreenOperation function. The series includes a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit. GreenOperation function provides high speed operation, low power consumption and high efficiencies by automatically switching between a high speed mode (HS) and a power save mode (PS) depending on the load current level. The switching point of the GreenOperation to the output current is being fixed inside the IC, thus providing operating conditions with the most suitable level of supply current for the application. The USP-6C package has GO pin. If a high level singal is input to the GO pin, the XC6416 can be used as a high speed fixed mode regulator. The EN function turns each output of the two regulators independently. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. Output voltage is selectable in 0.05V increments within a range of 0.8V ~4.0V, using laser trimming technologies. The series includes a fold-back circuit, which aids the operation of the current limiter and circuit protection.

OPERATIONAL DESCRIPTION
The voltage divided by resistors Rx1 & Rx2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET connected to the VOUT pin is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal.
< XC6416CD Series > XC6416C/D/G/H series can be set as a fixed high-speed (HS) mode or a green operation (GO) mode via a signal to the green operation (GO) pin. The IC operates in the GO mode when the GO pin becomes low level and the IC operates in the fixed high-speed mode when the GO pin becomes high level. The XC6416A/B/E/F series normally operates in GO mode because the GO signal is fixed to the VSS level inside the IC. The GO mode enables the IC to switch automatically the supply current to the high speed (HS) mode and the power save (PS) mode according to the level of output current. While having both high-speed operation and low supply current state, the series can acquire high efficiency. At the HS/PS automatic switching mode (GO mode), the switching point of the HS mode and the PS mode is being fixed inside the IC. When the output current becomes IGOR 1.5mA (TYP.) or below, the mode changes automatically to the PS mode after the delay time of hundreds s (TYP.), and it can reduce supply current in light load. Also when the output current becomes IGO 4mA (TYP.) or more, the mode changes automatically to the HS mode and the IC becomes high speed operation.
The XC6416 needs an output capacitor for phase compensation. The requested capacitance values are described in the table below. The device may go into unstable operation when the output capacitance reduction happens as a result of bias or temperature drift. Please choose a capacitor with less influence from temperature and bias. Also, please place 1.0 F input capacitor CL between VIN and VSS pins for stabilizing input supply voltage.

OPERATIONAL DESCRIPTION (Continued)
XC6416B/D/F/H series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the EN pin, which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL discharge resistance is set to 550 when VIN is 6.0V (TYP.) and VOUT is 4.0V (TYP.). Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value (CL) as ( =C x R), the output voltage after discharge via the N channel transistor is calculated by the following formulas. -t/ , or t= In ( V / VOUT ) V = VOUT x e V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time, : CL auto-discharge resistance R Output capacitor (CL) value C CL high-speed discharge function can be set by each regulator.
The XC6416 series includes a fold-back circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this drop in output voltage, output current also decreases. When the output pin is shorted, a current of about 20mA (TYP.) flows. The IC's internal circuitry can be shutdown via the signal from the EN pin with the XC6416 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via Rx1 & Rx2. However, as for the XC6416B/D/F/H series, the CL auto-discharge resistor is connected in parallel to Rx1 and Rx2 while the power supply is applied to the VIN pin. Therefore, time until the VOUT pin reaches the VSS level becomes short. The output voltage becomes unstable, when the EN pin is open. If this IC is used with the correct output voltage for the EN pin, the logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium voltage is input.
NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
