1A, 22V, Low IQ, Step-Down Converter Evaluation Board

The EV2322-D-00A evaluation board is designed to demonstrate the capabilities of MPS’s MP2322, a high light-load efficiency, synchronous, rectified, step-down, switch mode converter with built-in internal power MOSFETs. It offers a very compact solution to achieve 1A of continuous output current over a wide input supply range with excellent load and line regulation. The MP2322 switching edge is optimized for EMI reduction. Constnat-on-time (COT) control provides seamless mode transition and fast load transient response.

Full protection features include OCP, OVP, and thermal shutdown.

The MP2322 requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-8 (1.5mmx2mm) package.
