Monolithic Power Systems (MPS) EVQ4431-L-00A Evaluation Board

Monolithic Power Systems (MPS) EVQ4431-L-00A Evaluation Board is designed to evaluate the capabilities of the MP4431 and MPQ4431 switching voltage regulators. These regulators are frequency-configurable (350kHz to 2.5MHz), synchronous, and step-down switching regulators with integrated internal high-side and low-side power MOSFETs. The MP4431 and MPQ4431 regulators employ Advanced Asynchronous Mode (AAM) to achieve high efficiency under light-load conditions by scaling down the switching frequency.

The EVQ4431-L-00A evaluation board is a fully assembled and tested board that generates 3.3V of output voltage at load currents up to 1A. This evaluation board operates from 3.3V to 36V input voltage range with 450kHz switching frequency. The EVQ4431-L-00A evaluation board features low-dropout mode, configurable soft-start time, and power good indicator. This evaluation board is AEC-Q100 Grade 1 qualified for use in automotive and industrial power systems.
