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 is a fault tolerant magnetic
feedback circuit. Operating at a nominal fixed
frequency of 325 kHz per stage, these regulated,
isolated units utilize 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
Undervoltage Lockout
Indefinite Short Circuit Protection
Current Limit Protection

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