Io=3A non-isorated step-down DC/DC Converter module
MPM00 Series
Jul/10/2013
General Descriptions
The MPM series is a full molded hybrid IC which contains
a non-insulated buck type DC/DC converter in one
package. A power supply circuit can be composed in a
simple way by using this hybrid IC which requires a small
part count.
By connecting only an input smoothing electrolytic
capacitor, an output smoothing electrolytic capacitor and
an output voltage setting resistor, the hybrid IC can be
operated. Because of this simple composition, time
required for design evaluation is significantly reduced.
Since a power inductor is built in, it is not required to
select and evaluate the inductor separately. By adopting a
full molding package which can be fitted to the heat sink
by screwing, board mounting can be made in
self-supporting state without the heat sink subject to the
output voltage setting and load conditions.
