Product Highlights
Vicor’s MI-MegaMod family
of single, dual, and triple output
DC-DC converters provide power
system designers with cost-
effective, high-performance, off-
the-shelf solutions to applications
that might otherwise require a
custom supply.
Incorporating standard MI-200
or MI-J00 family converters in
rugged, chassis mount packages,
MegaMods can be ordered with
single, dual, or triple outputs,
having a combined output power
of up to 300W. Totally isolated
outputs eliminate efficiency
penalties and output interaction
problems.
