24V Input, 2A Module Synchronous Step-down Converter with Integrated Inductor and PG pin



The MPM3620A is a synchronous, rectified, step-down module converter with an integrated inductor, two capacitors, and power MOSFETs. It offers a compact solution that requires only 5 external components to achieve a 2 A 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). MPM3620A eliminates design and manufacturing risks while dramatically improving time-to-market. The MPM3620A is available in a space-saving QFN20 (3mm x 5mm x 1.6mm) package.
