OCP2156
1.
5MHz, 500mA Synchronous Step-Down Converter
◼ General Description
The OCP2156 is a 1.
5MHz constant frequency; slope
compensated 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 OCP2156 can supply
500mA of load current from a 2.
5V to 5.
5V input
voltage.
The output voltage can be regulated as low as
0.
6V.
The OCP2156 can also run at 100% duty cycle
for low dropout operation, extending battery life in
portable system.
Idle mode operation at light loads
