The Future of Analog IC Technology
The MPM3630 is a synchronous rectified, step-
down module regulator with built-in power
MOSFETs, inductor, and two capacitors. It
offers a very compact solution to achieve a 3A
continuous output current with excellent load
and line regulation over a wide input supply
range. The MPM3630 has a 1.4MHz switching
frequency, which provides fast load transient
Full protection features include over-current
protection (OCP) and thermal shutdown (TSD).
The MPM3630 eliminates design and
manufacturing risks while dramatically
The MPM3630 is available in a space-saving
QFN20 (3mmx5mmx1.6mm) package.
