EV4423A-Q-00A

3A, 36V, Synchronous Step-Down Converter Evaluation Board

Datasheet

Description

The EV4423A-Q-00A is an evaluation board for the MP4423A, MPQ4423A and MPQ4423A-AEC1, a family of high-frequency, synchronous, rectified, step-down, switch-mode converters with built-in power MOSFETs. It offers a very compact solution to achieve 3A of continuous output current, with excellent load and line regulation over a wide input supply range. The MP4423A/MPQ4423A/MPQ4423A-AEC1 have 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 EV4423A-Q-00A uses a minimal number of readily available, standard external components, and is assembled and tested in space-saving QFN-8 (3mmx3mm) package.
