MPQ4423A-AEC1

MPQ4423A-AEC1

AEC1-Automotive Grade, High Efficiency, Force CCM Mode, 3A, 36V, Synchronous Step Down Converter with PG and Ext. Sync

Datasheet

Description

The MPQ4423A is a high-efficiency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact 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. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown. The MPQ4423A requires a minimal number of readily available, standard, external components and is available in a compact QFN-8 (3mmx3mm) package.
