The EVBL4571-QB-00A is an evaluation board designed to demonstrate the capabilities of the MP4571, a high-efficiency, synchronous step-down converter with integrated, internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). Using an MPS power inductor, the device can deliver up to 1A of continuous output current (IOUT), with peak current control for excellent transient response.
The MP4571 features advanced asynchronous modulation (AAM) mode and forced continuous condition mode (FCCM). AAM helps achieve high efficiency under light-load conditions by scaling back the switching frequency (fSW) to reduce switching and gate driver losses.
The EVBL4571-QB-00A is a fully assembled and tested evaluation board. It generates 5V of output voltage (VOUT) and 1A of continuous IOUT across a wide 5V to 60V input range.
The MP4571 is available in a QFN-12 (2.5mmx3mm) package.
