Overview

TopologyBuck Converter
Input voltage12 V
Output 15 V / 6 A
IC revision1.0

Description

The EVQ4423C-L-00A evaluation board is designed for the MPQ4423C, a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in power MOSFETs. The device offers a very compact solution to achieve 6A of peak output current with excellent load and line regulation across a wide input supply range. The MPQ4423C has synchronous mode operation for higher efficiency across the output current load range.
