MP4420H - Synchronous Step-Down Converter

General Description

The MP4420H 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 2A 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 MP4420H requires a minimal number of readily-available standard external components, and is available in a space-saving TSOT23-8 package.

The Future of Analog IC Technology DESCRIPTION The MP4420H 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 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP4420H 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 MP4420H requires a minimal number of readily-available standard external components, and is available in a space-saving TSOT23-8 package.
