MPM3632C Step-Down Converter with Integrated Inductor

MPS' MPM3632C 18 V input, 3 A module, synchronous, forced CCM, step-down converter with integrated inductor

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

The MPM3632C eliminates design and manufacturing risks while improving the time to market dramatically. Full protection features include output overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown. The MPM3632C is available in a space-saving QFN-20 (3 mm x 5 mm x 1.6 mm) package.
