High Reliability
The DV200 series of high reliability, isolated DC-DC
converters is operable over a wide (-55 °C to +100
°C) temperature range with no power derating.
Unique to the DV200 series is a magnetic feedback
circuit that is radiation immune. Operating at a
nominal fixed frequency of 500 kHz, these regulated,
isolated units utilize well-controlled undervoltage
lockout circuitry to eliminate slow start-up problems.
The current sharing function allows a maximum of
five units to be connected in parallel to boost the
total output power to 5 times. The output voltage is
trimmable up to +10% or down –20%.
Parallel Up to 5 Units With Current Sharing
Output Voltage Trim Up +10% or Down –20%
Wide Input Voltage Range: 16 to 50 Volts
Up to 200 Watts Output Power
Radiation Immune Magnetic Feedback Circuit
NO Use of Optoisolators
Undervoltage Lockout
Input Transient Voltage: 55 Volts for 1 second
High Power Density: ≈ 80 W/in3
Custom Versions Available
Additional Environmental Screening Available
Meets MIL-STD-461C and MIL-STD-461D EMC
Requirements When Used With a DVME28 EMI
Filter
These converters are designed and manufactured in
a facility qualified to ISO9001, compliant to AS9000,
and certified to MIL-PRF-38534 and MIL-STD-883.

OUTPUT VOLTAGE TRIM
The output voltage can be trimmed down by
connecting a resistor between the TRIM pin
(PIN 8) and the +V OUT pin (PIN 6), or can
be trimmed up by connecting a resistor
between the TRIM pin (PIN 8) and the OUT
COM pin (PIN 10). The maximum trim
range is +10% up and –20% down. The
appropriate resistor values versus the
output voltage are given in the trim table
below.
