HIGH RELIABILITY HYBRID DC-DC CONVERTERS

Delta Electronics, Inc. 

OUTPUT VOLTAGE TRIM

DVHE2800S Series

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.
