MP2119

2A, 6V Synchronous

Step-Down Switching Regulator

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

2A Output Current

The MP2119 is an internally compensated

1.5MHz fixed frequency PWM synchronous

step-down regulator. MP2119 operates from a

2.7V to 6V input and generates an output

voltage as low as 0.8V.

Input Operation Range: 2.7V to 6V

All Ceramic Capacitor Design

1.5MHz Fixed Switching Frequency

Adjustable Output from 0.8V to 0.9xV_IN

Internal Soft-Start

Frequency Synchronization Input

Power Good Output

Thermal Shutdown

The MP2119 integrates a 100mΩ high-side

switch and a 100mΩ synchronous rectifier for

high efficiency without an external Schottky

diode. With peak current mode control and

internal compensation, the MP2119 based

solution delivers a very compact footprint with a

minimum component count.

Cycle-by-Cycle Current Limiting

Hiccup Short Circuit Protection

3mm x 3mm QFN Package

The MP2119 is available in a small 3mm x 3mm

QFN package.
