MPM3632S from Monolithic Power Systems is a synchronous, rectified, step-down, mini-module regulator with built-in power MOSFETs, an inductor, and two capacitors. It offers a compact solution with only input and output capacitors to achieve a 3 A continuous output current with excellent load and line regulation over a wide input supply range. The device operates in a fixed 2.2 MHz switching frequency with constant on-time (COT) control to provide a fast load transient response. The MPM3632S offers full protection features, including output overvoltage protection (OVP), overcurrent protection (OCP), and thermal shut down. The MPM3632S is available in an EC LGA-10 (3 mm x 3 mm x 1.45 mm) package.
