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 high speed
magnetic feedback circuit. 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%.
Output Voltage Trim Up +10% or Down –20%
Wide Input Voltage Range: 16 to 50 Volts
Up to 200 Watts Output Power
Up to 70% of Rated Output Power is Available
for Each Output
Fault Tolerant Magnetic Feedback Circuit
NO Use of Optoisolators
Undervoltage Lockout

OUTPUT VOLTAGE TRIM
The output voltage can be trimmed down by
connecting a resistor between the TRIM pin
(PIN 9) and the +V OUT pin (PIN 6), or can
be trimmed up by connecting a resistor
between the TRIM pin (PIN 9) and the OUT
COM pin (PIN 8). 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.
