Product Highlights
Vicor’s 2nd Generation DC-DC
converters represent a quantum
leap in the performance and
flexibility of power components.
With advanced power processing,
control, and packaging technologies,
power density has tripled while
reducing the cost per Watt of
processed power. A high level of
silicon integration reduces parts
count to less than a third of
1st Generation converters,

increasing reliability.
Fully encapsulated, Vicor 2nd
Generation modules utilize a
proprietary spin fill process that
assures complete, void free
encapsulation making them
suitable for the most harsh
military environments. Two
military grades (H & M) are
available with temperatures to
-55°C operating and -65°C
storage. H & M-grade modules
have been subjected to the
environmental testing requirements
of MIL-STD-810, MIL-S-901, and
MIL-STD-202 and undergo 100%
environmental stress screening.
