MP2238

High-Efficiency, 8A, 18V,

Synchronous Step-Down Converter

DESCRIPTION

FEATURES

The MP2238 is a high frequency, synchronous,

rectified, step-down switch-mode converter. It

offers a fully integrated solution to achieve an

8A continuous output current with excellent load

and line regulation over a wide input supply

range.



Wide 4.2V to 18V Operating Input Range

8A Continuous Output Current

22mΩ/10mΩ Low R_DS(ON)Internal Power

MOSFETs

Default 600mV Reference Voltage

Adjustable Output Voltage

600kHz Switching Frequency

Ton Extension



Constant-on-time (COT) control operation

provides fast transient response. Full protection

features include hiccup over-current protection

and thermal shutdown.

Hiccup OCP Protection

Thermal Shutdown Protection

Available in a 12-Pin QFN 2mmx3mm

Package

The MP2238 requires a minimal number of

readily

available,

standard,

external

components with a space-saving 12-pin QFN

2mmx3mm package.

APPLICATIONS



Flat-Panel Television and Monitors

Digital TV Power Supply

Digital Set-Top Boxes

Distributed Power Systems
