MP2120DQ Datasheet 5.5v Synchronous Step-down Switching Regulator

Manufacturer: Monolithic Power Systems

Overview: The Future of Analog IC Technology.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MP2120 is an internally pensated 1.5MHz fixed frequency PWM synchronous step-down regulator.

MP2120 operates from a 2.7V to 5.5V input and generates an output voltage as low as 0.8V.

The MP2120 integrates an 80mΩ high-side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode.
