EV4423-Q-00A

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

Datasheet

Description

The EV4423-Q-00A is an evaluation board for the MP4423/MPQ4423, a high-frequency, synchronous, rectified, step-down, switch-mode converter 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 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 shutdown.

The EV4423-Q-00A uses a minimal number of readily available, standard external components, and is assembled and tested in a space-saving QFN-8 (3mmx3mm) package.

How to protect MPQ4423H against Burst and Surge at VIN=30V?

We want to use MPQ4423H (like in Evalboard EV4423H). VINmin=10V and VINmax=30V. A TVS-diode (SMCJ28CA) does not protect the chip beacuse of the high.....
