MP2208

16V, 4A, 600kHz Synchronous

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2208 is an internally compensated

600kHz fixed frequency PWM synchronous

step-down regulator. With a 3V to 6V bias

supply, MP2208 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

Stable with Ceramic Output Capacitors

High Efficiency

600kHz Fixed Switching Frequency

Adjustable Output from 0.8V to 0.9xV_IN

Frequency Synchronization

Power Good Pin

The MP2208 integrates a 80mΩ high-side

switch and a 80mΩ synchronous rectifier for

high efficiency without an external Schottky

diode. With peak current mode control and

internal compensation, it can be stabilized with

ceramic capacitors and small inductors. Fault

condition protection includes short-circuit

protection, cycle-by-cycle current limiting and

thermal shutdown.
