High Reliability
Very Low Output Noise
The DVSA 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 DVSA 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.
Wide Input Voltage Range: 15 to 50 Volts per
MIL-STD-704
Up to 6 Watts Output Power
Fault Tolerant Magnetic Feedback Circuit
NO Use of Optoisolators
Undervoltage Lockout

Indefinite Short Circuit Protection
Current Limit Protection
Industry Standard Pinout
High Input Transient Voltage: 80 Volts for 1 sec
per MIL-STD-704A
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-
PRF-38534 and MIL-STD-883.
