EV4581-N-00A

100V, 0.8A Synchronous Buck Converter

Datasheet

Description

The EV4581 Evaluation Board is designed to demonstrate the capabilities of MPS’ MP4581. The MP4581 is a high efficiency synchronous
step-down converter with integrated high-side and low-side MOSFETs. It provides 0.8A output in buck topology from up to 100V input power
supply.

MP4581 supports high efficiency pulse-skipmode (PSM) in light load condition. Valley current limit circuits protect against overload
and short circuit conditions.

The MP4581 is available in a SOIC8EP packages.
