MP2229

High Efficiency 21V, 6A

Synchronous Step-Down Converter with External

Sync, Low-Power Mode, and External Soft-Start

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2229 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with internal power MOSFETs. It offers a

compact solution to achieve a 6A continuous

output current over a wide input-supply range

with excellent load and line regulation. The

MP2229 has synchronous-mode operation for

higher efficiency over the output current load

range.
