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
475 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 40 Watts Output Power
Fault Tolerant Magnetic Feedback Circuit
Output Voltage Trim Up +10%
NO Use of Optoisolators
Undervoltage Lockout
