EVQ4576-QB-00A

EVQ4576-QB-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4576 and MPQ4576-AEC1, which are fully integrated, fixed-frequency, synchronous step-down converters. They can achieve up to 0.6A of continuous output current (IOUT) with peak current control mode for excellent transient response. Advanced asynchronous modulation (AAM) mode achieves high efficiency under light-load conditions by scaling down the frequency to reduce switching and gate driver losses. The EVQ4576-QB-00A is a fully assembled and tested evaluation board that generates up to 5V of output voltage (VOUT) and up to 0.6A of load current across a wide 5V to 60V input voltage (VIN) range. The MPQ4576-AEC1 is available in a QFN-12 (2.5mmx3mm) package, and is AEC-Q100 qualified.
