Product Description

The MPM3606A is a synchronous rectified, step-down module converter with built-in power MOSFETs, inductor, and two capacitors. It offers a compact solution that requires only 5 external components to achieve a 0.6A continuous output current with excellent load and line regulation over a wide input-supply range. Also, it provides fast load transient response. Full protection features include over-current protection (OCP) and thermal shutdown (TSD). MPM3606A eliminates design and manufacturing risks while dramatically improving time-to-market. The MPM3606A is available in a space-saving QFN20 (3mmx5mmx1.6mm) package.
