Monolithic Power Systems (MPS) EVQ4576 Evaluation Board

Monolithic Power Systems (MPS) EVQ4576 Evaluation Board is designed to demonstrate the capabilities of the MPQ4576 and MPQ4576-AEC1, which are fully integrated, fixed-frequency, and synchronous step-down converters. This evaluation board operates at 5V output voltage, 5V to 60V input voltage range and up to 0.6A of continuous output current with peak current control for the transient response. The EVQ4576 board features Advanced Asynchronous Modulation (AAM) mode achieving efficiency under light-load conditions by scaling down the frequency to reduce switching and gate driver losses. Typical applications include automotive systems and industrial power systems.
