On single output units, an external resister may be added to
adjust the converter output.
To adjust the output UP, connect a 5%, 3W resistor between
the minus output pin (5) and the Vout trim pin (6). To adjust
the output DOWN, connect a 5%, 3W resistor between the plus
output pin (4) and the Vout trim pin (6).
The trim table at right gives suggested resistor values for
this adjustment.
