OCP2161 - 800mA Synchronous Step-Down Converter

Download the OCP2161 datasheet PDF. This datasheet also covers the OCP2161-ORIENT variant, as both devices belong to the same 800ma synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The OCP2161 contains two independent 1.5MHz constant frequency, current mode, PWM step-down converters.

Each converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode.

WWW.ORIENT-CHIP.COM OCP2161 Dual 1.5MHz, 800mA Synchronous Step-Down Converter ◼ General Description The OCP2161 contains two independent 1.5MHz constant frequency, current mode, PWM step-down converters. Each converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The OCP2161 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 800mA of load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. The OCP2161 can also run at 100% duty cycle for low dropout applications. ◼ Pin Configuration TOP VIEW ◼ Features ⚫ Up to 95% Efficiency ⚫ 1.5MHz Constant Switching Frequency ⚫ 800mA Load Current on Each Channel ⚫ 2.
