3A, 36V, Synchronous Step Down Converter Evaluation Board
Learn about our Evaluation Kit
Product Description
The EV4423A-Q-00A is an evaluation board for the MP4423A, MPQ4423A and MPQ4423A-AEC1, 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 MP4423A/MPQ4423A/MPQ4423A-AEC1 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 thermalshut down.
The EV4423A-Q-00A uses a minimal number of readily-available standard components, and is assembled and tested in space-saving QFN-8 (3mmx3mm) package.
