Description
The MPM80, MPM81, and MPM82 are hybrid module ICs that
include a non-isolated step-down DC / DC converter circuit with
an inductor in a full-mold package. These features allow simple
circuit configurations using few components, contributing to
a reduction in design time and PCB space.
This product can operate by simply connecting an input
smoothing capacitor, an output smoothing capacitor, and
output voltage setting resistors. This contributes to a reduction
in man-hours for design and evaluation. Because this product
contains a power inductor, the burdensome work of selecting
and evaluating an inductor is unnecessary.
Adoption of the free-standing full-mold package provides the
design flexibility of either screwing the package to a heatsink
or mounting the package directly on a PCB substrate without
installing a heatsink, depending on the output voltage setting
and load conditions.
