MP2214

16V, 4A, 600kHz Synchronous

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2214 is an internally compensated

600kHz fixed frequency PWM synchronous

step-down regulator with a 3V to 6V bias supply

(V_CC). MP2214 operates from a 3V to 16V input

and generates an adjustable output voltage

from 0.8V to 0.9xV_INat up to 4A load current.

4A Output Current

Input Supply Range: 3V to 16V

80mΩ Internal Power MOSFET Switches

All Ceramic Output Capacitors Design

Up to 95% Efficiency

600kHz Fixed Switching Frequency

Adjustable Output from 0.8V to 0.9xV_IN

Internal Soft-Start

Power Good Pin

Frequency Synchronization Input

Thermal Shutdown

The MP2214 integrates an 80mΩ high-side

switch and an 80mΩ synchronous rectifier for

high efficiency without an external Schottky

diode. With peak current mode control and

internal compensation, it is stable with a output

ceramic capacitor and a small inductor. Fault

protection, cycle-by-cycle current limiting and

thermal shutdown. Other features include

frequency synchronization and internal soft-

start.

APPLICATIONS

The MP2214 is available in small 3mm x 4mm

14-lead QFN and 8-lead SOIC with exposed

pad packages.
