High Efficiency, Up to 90%
Low Output Voltage Models
The DVHE series of high reliability DC-DC
converters is operable over the full military (-55 °C to
+125 °C) temperature range with no power derating.
Operating at a fixed frequency, these regulated,
isolated units utilize well controlled undervoltage
lockout circuitry to eliminate slow start-up problems.
Up to 50 Watts Output Power
Up to 10 Amps Output Current
High Reliability
Very Low Output Noise
Wide Input Voltage Range: 16 to 40 Volts
Input Transient Voltage: 50 Volts for 1 sec
Output Voltage Trim +/-10%
NO Use of Optoisolators
The DVHE is optimized for low voltage applications
with high efficiency synchronous rectification and fast
transient response.
Undervoltage Lockout
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-
PRF-38534 and MIL-STD-883.
Short Circuit / Current Limit Protection
High Power Density: > 50 W/in3
Industry Standard Package
Precision Seam Seal Hermetic Package
Flanged and Non-flanged Versions Available.

OUTPUT VOLTAGE TRIM
The output voltage can be trimmed down by
connecting a resistor between the TRIM pin
(PIN 2) and the +V OUT pin (PIN 5), or can
be trimmed up by connecting a resistor
between the TRIM pin (PIN 2) and the OUT
COM pin (PIN 4). The maximum trim range
is +10% up and –10% down. The
appropriate resistor values versus the
output voltage are given in the trim table
below.
