DESCRIPTION
FEATURES

High Reliability
Very Low Output Noise
The DVTR 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 DVTR 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 30 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 Seam Welded Hermetic Package
High Power Density: > 28 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 DVTR2800T 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. SMDs 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
represents the Federal Stock Class, Device Type, Device Class Designator, Case Outline, Lead Finish
and RHA Designator (where applicable). 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.
