MPM3509B is a synchronous, rectified, step-down converter power module with built-in power MOSFETs, inductors and capacitors. The MPM3509B offers a very compact solution and requires only four external components to achieve 0.6A of continuous output current with excellent load and line regulation over a wide input supply range. The MPM3509B operates with a 400KHz switching frequency to achieve a fast load transient response. Full protection features include overcurrent protection (OCP) with valley current detection and hiccup mode and thermal shutdown. The MPM3509B eliminates design and manufacturing risks while dramatically improving time-to-market. The MPM3509B is available in a space-saving QFN-17 (3mmx5mmx1.6mm) package. Typical applications include automotive infotainment, automotive clusters, automotive telematics, medical and imaging equipment, distributed power systems.
