MP9943GQ - Synchronous Step Down Converter

Download the MP9943GQ datasheet PDF. This datasheet also covers the MP9943 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 MP9943 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 peak output current with excellent load and line regulation over a wide input supply range.

Key Features

  • include over-current protection and thermal shutdown. The MP9943 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 MP9943 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 peak output current with excellent load and line regulation over a wide input supply range. The MP9943 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 shutdown. The MP9943 requires a minimal number of readily-available standard external components, and is available in a space-saving QFN-8 (3mmx3mm) package.
