General Description

The MP4581 is a high-efficiency, synchronous step-down converter with integrated power MOSFETs.

It provides 0.8A of output current (IOUT) in a buck topology from an input power supply of up to 100V.

The MP4581

Overview

MP4581 100V, 0.8A, High-Efficiency, Synchronous, Step-Down Buck Converter with Integrated Power.

Key Features

  • constant-on-time (COT) control, which provides fast transient response and facilitates loop stabilization. The configurable operation frequency can be set between 100kHz to 1MHz via an external resistor. The MP4581 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 MP4581 is available in an SOIC-8EP package.
