DVPL0505S Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
The DVPL series of high reliability DC-DC converters
is operable over the full military (-55 °C to +125 °C)
temperature range with no power derating.
Operating at a nominal fixed frequency of 300 kHz,
these regulated, non-isolated converters are
optimized for low voltage point of load applications
with high efficiency synchronous rectification, fast
transient response, and power sequencing
capability.
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-
PRF-38534 and MIL-STD-883.
This product may incorporate one or more of the
following U.S. patents:
