Datasheet Summary
1.5 MHz, 600mA Synchronous Step-Down Converter With Low Quiescent Current
Product Description
GS5571 is a 1.5Mhz constant frequency, slope pensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. The GS5571 can supply 600mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The GS5571 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Idle mode operation at light loads provides...
