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 (I_OUT), with peak current control for excellent transient response.

The MP4571 features advanced asynchronous modulation (AAM) mode and forced continuous condition mode (FCCM). AAM mode achieves high efficiency under light-load conditions by scaling back the switching frequency (f_SW) 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 (V_OUT) and up to 1A of continuous I_OUT across a wide 5V to 60V input voltage (V_IN) range. The MP4571 is available in a QFN-12 (2.5mmx3mm) package.
