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: 160 to 400 Volts
Up to 175 Watts Output Power
Radiation Immune Magnetic Feedback Circuit
NO Use of Optoisolators
Undervoltage Lockout
Indefinite Short Circuit Protection
Current Limit Protection
Input Transient Voltage: 500 Volts for 1 second
High Power Density: ≈ 80 W/in3
Custom Versions Available
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-
PRF-38534 and MIL-STD-883.
Additional Environmental Screening Available

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.
