High Reliability
Very Low Output Noise
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 325 kHz,
per stage, these regulated, isolated units utilize a
high speed magnetic feedback design and well
controlled undervoltage lockout circuitry to eliminate
slow start-up problems.
Wide Input Voltage Range: 15 to 50 Volts per
MIL-STD-704
Up to 15 Watts Output Power
Fault Tolerant Magnetic Feedback Circuit
NO Use of Optoisolators

Industry Standard Pinout
High Input Transient Voltage: 80 Volts for 1 sec
per MIL-STD-704A
Precision Projection Welded Hermetic Package
High Power Density: > 37 W/in3
Custom Versions Available
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-
PRF-38534 and MIL-STD-883.

Do not use the DVHF+2800T 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
https://landandmaritimeapps.dla.mil/programs/defaultapps.asp. The SMD number listed above is for
MIL-PRF-38534 Class H screening, 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.
