EVBL4571-QB-00A

EVBL4571-QB-00A is an evaluation board designed to demonstrate the capabilities of the MP4571, a high-efficiency, synchronous stepdown converter with integrated internal power MOSFETs (HS-FET and LS-FET, respectively). It can deliver up to 1A of continuous output current, with peak current control for excellent transient response and an integrated MPS power inductor. The MP4571 features advanced asynchronous mode (AAM) 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 output current across a wide 5V to 60V input range. Typically used in automotive systems and industrial power systems.
