Monolithic Power Systems (MPS) EVQ2178 Evaluation Board

Monolithic Power Systems (MPS) EVQ2178 Evaluation Board is designed to demonstrate the capabilities of the MPQ2178. The MPQ2178 is a monolithic, step-down, switch-mode converter with integrated internal power MOSFETs. This evaluation board operates a 2A continuous output current across a 2.5V to 5.5V input voltage range, with excellent load and line regulation and regulating 0.6V output voltage. The EVQ2178 evaluation board features fault protections, including cycle-by-cycle current limiting and thermal shutdown.
