High Reliability
Very Low Output Noise
The DVWR 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 DVWR 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 25 Watts Output Power
Fault Tolerant Magnetic Feedback Circuit
NO Use of Optoisolators
