MP2112DJ - 1A Synchronous Step-Down Converter

Download the MP2112DJ datasheet PDF. This datasheet also covers the MP2112 variant, as both devices belong to the same 1a synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP2112 is a 1MHz constant frequency, 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 powered by a single cell Lithium-Ion (Li+) battery.
