Monolithic Power Systems (MPS) EV4583-QVE-00C Evaluation Board
Monolithic Power Systems (MPS) EV4583-QVE-00C Evaluation Board is designed to demonstrate the capabilities of the MP4583 synchronous step-down DC/DC converter. The board supports a 4.5V to 100V input range and delivers up to 3A of output current. EV4583-QVE-00C provides a convenient platform for evaluating efficient power conversion, integrated MOSFET performance, and converter operation across a wide load range.
The evaluation board highlights the MP4583's low 8μA quiescent current, fixed 400kHz switching frequency, and selectable Power-Save Mode (PSM) or Forced Continuous Conduction Mode (FCCM) operation. Internal compensation, soft-start functionality, and Power Good (PG) indication simplify testing and development. Typical efficiency reaches 92.3%, while peak efficiency can achieve 96.5%, making the board suitable for validating high-efficiency power supply designs.
