Feature Descriptions
Remote On/Off
Remote Sense
Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections. The voltage between the remote-sense
pins and the output terminals must not exceed the out-
put voltage sense range given in the Feature Specifica-
tions table, i.e.:
The voltage between the V
must not exceed 5.9 V. This limit includes any increase
in voltage due to remote-sense compensation and out-
put voltage set-point adjustment (trim), see Figure 15.
If not using the remote-sense feature to regulate the
output at the point of load, then connect SENSE(+) to
V

Output Voltage Set-Point Adjustment
(Trim)
Output voltage trim allows the user to increase or
decrease the output voltage set point of a module. This
is accomplished by connecting an external resistor
between the TRIM pin and either the SENSE(+) or
SENSE(–) pins. With an external resistor between the
TRIM and SENSE(–) pins (R
set point (V
ing equation determines the required external-resistor
value to obtain a percentage output voltage change of
Δ%.
The test results for this configuration are displayed in
Figure 17. This figure applies to all output voltages.

change of Δ%.
The test results for this configuration are displayed in

The voltage between the V

in voltage due to remote-sense compensation and out-
put voltage set-point adjustment (trim). See Figure 15.
If not using the trim feature, leave the TRIM pin open.
