MPQ4423HGQ - Synchronous Step Down Converter

Download the MPQ4423HGQ datasheet PDF. This datasheet also covers the MPQ4423H variant, as both devices belong to the same synchronous step down converter family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.

The Future of Analog IC Technology 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.
