Product Description

The EV4423-Q-00A is an evaluation board for the MP4423/MPQ4423, a high-frequency, synchronous, rectified, step-down, switch-mode converter with build-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 MP4423/MPQ4423 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 EV4423-Q-00A uses a minimal number of readily-available standard components, and is assembled and tested in space-saving QFN-8 (3mmx3mm) package.
