Monolithic Power Systems MP8716

High Efficiency 3A, 21V, 500kHz Synchronous Step-down Converter

Overview

TopologyBuck Converter
Input voltage8-21 V
Switching frequency425-575 kHz
Output 11.2 V / 3 A
IC revision0.9

Description

The MP8716 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 3A continuous output current over a wide input supply range with excellent load and line regulation. The MP8716 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 MP8716 requires a minimum number of readily available standard external components and is available in a space saving 8-pin SOIC package with an exposed pad.
