Monolithic Power Systems (MPS) EVQ4571-QB-00A Buck Converter Evaluation Board
Monolithic Power Systems (MPS) EVQ4571-QB-00A Buck Converter Evaluation Board demonstrates the capabilities of the MPQ4571 / MPQ4571-AEC1 fully integrated, fixed-frequency, synchronous step-down converters. The MPQ4571 / MPQ4571-AEC1 employs advanced asynchronous mode (AAM) to achieve high efficiency under light-load conditions by scaling down the switching frequency. The scale down reduces switching and gate-driving losses. The fully assembled and tested EVQ4571-QB-00A evaluation board generates a 5V output voltage at load currents up to 1A from a 5V to 60V input range.
