MP2120

2.5A, 5.5V Synchronous

Step-Down Switching Regulator

The Future of Analog IC Technology

DESCRIPTION

FEATURES



2.5A Output Current

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.

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 0.9xV_IN

Internal Soft-Start

Frequency Synchronization Input

Power Good Output

Cycle-by-Cycle Current Limiting

Hiccup Short Circuit Protection

Thermal Shutdown

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.

3mm x 3mm 10-lead QFN Package

The MP2120 is available in a small 3mm x 3mm

10-lead QFN package.

APPLICATIONS
