MP2120

2.5A 5.5V Synchronous Step-Down Switching Regulator

Newer version available

Datasheet

Description

The MP2120 is an internally compensated 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. With peak current mode control and internal compensation, the MP2120 based solution delivers a very compact footprint with a minimum component count. The MP2120 is available in a small 3mm x 3mm 10-lead QFN package.
