MPQ4423H

Industrial Grade, High Efficiency 3A, 36V, Synchronous Step Down Converter with PG and Ext. Sync

Active

Datasheet

Description

The MPQ4423H is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 3A continuous output current with excellent load and line regulation over a wide input supply range. The MPQ4423H has synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection and thermal shut down. The MPQ4423H requires a minimal number of readily-available standard external components, and is available in a space-saving QFN-8 (3mmx3mm) package.
