High Reliability
Very Low Output Noise
The DVCH 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 DVCH 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 400 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: 12 to 50 Volts per
MIL-STD-704
Up to 1.5 Watts Output Power
Fault Tolerant Magnetic Feedback Circuit
