21V Input, 1.2A Module Synchronous Step-down Converter with Integrated Inductor and PG pin



The MPM3610A is a synchronous rectified, step-down module converter with built-in power MOSFETs, inductor, and two capacitors. It offers a very compact solution, requires only 5 external components to achieve a 1.2A continuous output current with excellent load and line regulation over a wide input supply range and provides fast load transient response. Full protection features include over-current protection and thermal shut-down. MPM3610A eliminates design and manufacturing risks while dramatically improving time-to-market. The MPM3610A is available in a space-saving QFN20 (3mmx5mmx1.6mm) package.
