Monolithic Power Systems MP2322 | Demoboard EV2322-D-00A

Description

The EV2322-D-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP2322, a high light load efficiency synchronous rectified step-down switch modeconverter with built in internal power MOSFETs. It offers a very compact solution to achieve 1A continuous output current over a wide input supply range with excellent load and line regulation.The MP2322 switching edge is optimized for EMI reducing. COT (Constant On Time) control provides seamless mode transition and fast load transient response. Full protection features include OCP, OVP and thermal shut down.The MP2322 requires 7 of readily available standard external components and is available in a space saving QFN-8(1.5mmx2mm) package.
