MPS Sychronous Step-Down Module

18V Input, 3A Module, Synchronous, Forced CCM, Step-Down Converter with Integrated Inductor

The MPM3632C, by Monolithic Power Systems (MPS), is a step-down regulator module integrated with a synchronous, rectifying power MOSFET, an inductor and three capacitors. The MPM3632C offers a very compact solution that requires only input and output capacitors to achieve 3A of continuous output current with excellent load and line regulation over a wide input range. The MPM3632C operates at a fixed 3MHz switching frequency and employs constant-on-time (COT) control, which provides a fast load transient response.


Shorter development stage and more portection

The MPM3632C eliminates design and manufacturing risks while improving the time to market dramatically. Full protection features include output over-voltage protection (OVP), over-current protection (OCP) and thermal shutdown. The MPM3632C is available in a space-saving QFN-20 (3x5x1.6mm) package.
