HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
The DVHF series of high reliability DC-DC converters
is operable over the full military (-55 °C to +125 °C)
temperature range with no power derating. Unique
to the DVHF series are robust and effective input and
output filters which provide dramatically reduced
input and output noise performance when compared
to other manufacturers competing devices.
Operating at a nominal fixed frequency of 450 kHz,
these regulated, isolated units utilize a high speed
magnetic feedback design and well controlled
undervoltage lockout circuitry to eliminate slow start-
up problems.
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:

Do not use the DVHF2800S Series similar part number for SMD product acquisition. It is listed for
reference only. For exact specifications for the SMD product, refer to the SMD drawing. SMD’s can be
downloaded from the DLA Land and Maritime (Previously known as DSCC) website at
http://www.dscc.dla.mil/programs/smcr/. The SMD number listed above is for standard gold plated lead
finish and no RHA (Radiation Hardness Assurance) level. Please reference the SMD for other
screening levels, lead finishes, and radiation levels. All SMD products are marked with a “Q” on the
cover as specified by the QML certification mark requirement of MIL-PRF-38534.
