Monolithic Power Systems MP8771 | Demoboard EV8771-Q-00A

High-Efficiency, 700kHz, 10A, 17V Step-Down Converter Evaluation Board

Overview

TopologyBuck Converter
Input voltage12 V
Output 11 V / 10 A
IC revision1.0

Description

MPS’ MP8771, a fully-integrated high-frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 10A continuous output current over a wide input range, with excellent load and line regulation. The MP8771 has synchronous-mode operation for higher efficiency over the output current-load range
