MPQ4423AGQ Overview
The MPQ4423A is a high-efficiency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very pact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input supply range. The MPQ4423A uses synchronous mode operation to achieve higher efficiency over the output current load range.
