MP4588

100V, 0.8A, High-Efficiency, Synchronous Step-Down Converter with Integrated Power MOSFETs

Description

The MP4588 is a high-efficiency, synchronous, step-down converter with integrated power MOSFETs. It provides 0.8A of output current (I_OUT) in a buck topology from an input power supply of up to 100V.

The MP4588 features constant-on-time (COT) control, which provides fast transient response and facilitates loop stabilization.

The MP4588 supports high-efficiency pulse-skip mode (PSM) while operating under light-load conditions. The valley current-limit circuits protect against overload and short-circuit conditions.

The MP4588 is available in a QFN-14L (3mmx3mm) package.
