Automotive Grade, 1.5A, 36V, Synchronous Step-Down Power Module with Integrated Inductor and Power Good,



The MPM3515-AEC1 is a synchronous, rectified, step-down converter with built-in power MOSFETs, inductors, and capacitors. The MPM3515-AEC1 offers a very compact solution and requires only four external components to achieve 1.5A of continuous output current with excellent load and line regulation over a wide input supply range. The MPM3515-AEC1 operates with a 2.2MHz switching frequency to achieve a fast load transient response. Full protection features include over-current protection (OCP) and thermal shutdown. The MPM3515-AEC1 eliminates design and manufacturing risks while improving the time to market dramatically. The MPM3515-AEC1 is available in a space-saving QFN-17 (3mmx5mmx1.6mm) package.
