Monolithic Power Systems (MPS) - MPM3506A

MPM3506A - power module for industrial applications

MPS MPM3506A component visualization

The MPM3506A is a synchronous, rectified, step-down converter with built-in power MOSFETs, inductor, and two capacitors. It offers a compact solution with only 4 external components to achieve a 0.6A continuous output current with excellent load and line regulation over a wide input supply range. The MPM3506A operates in a 1.15MHz switching frequency, which provides fast load transient response. Full protection features include over-current protection (OCP) and thermal shutdown (TSD). The MPM3506A eliminates design and manufacturing risks while dramatically improving time-to-market. The MPM3506A is available in a space-saving QFN-19 (3mmx5mmx1.6mm) package.
