Description

General part information

MP2120 Series

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 80m? high-side switch and a 60m? 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.2.5A Output Current Input Operation Range: 2.7V to 5.5V All Ceramic Capacitor Design Up to 95% Efficiency 1.5MHz Fixed Switching Frequency Adjustable Output from 0.8V to 0.9xVIN Internal Soft-Start Frequency Synchronization Input Power Good Output Cycle-by-Cycle Current Limiting Hiccup Short Circuit Protection Thermal Shutdown 3mm x 3mm 10-lead QFN Package
