Monolithic Power Systems MP28252

High Efficiency 2A, 21V, 500kHz Synchronous Step-down Converter

Overview

TopologyBuck Converter
Input voltage6-21 V
Output 112 V / 2 A
IC revision1.11

Description

The MP28252 is a high frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs. It offers a very compact solution to achieve 2A continuous output current over a wide input supply range with excellent load and line regulation. The MP28252 has synchronous mode operation for higher efficiency over output current load range.

Current mode operation provides fast transient response and eases loop stabilization.

Full protection features include OCP and thermal shut down.

The MP28252 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package.
