OCP2157
1.
5MHz, 700mA Synchronous Step-Down Converter
◼ General Description
The OCP2157 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 OCP2157 can supply 700mA of load current from a 2.
5V to 5.
5V input
voltage.
The output
voltage can be regulated as low as 0.
6V.
The OCP2157 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system.
