Feature Descriptions
Remote Sense
The voltage between the V
must not exceed the minimum output overvoltage shut-
down value indicated in the Feature Specifications
table. This limit includes any increase in voltage due to
remote-sense compensation and output voltage set-
point adjustment (trim). See Figure 20.
If not using the remote-sense feature to regulate the
output at the point of load, then connect SENSE(+) to
V
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. Consult the factory if you
need to increase the output voltage more than the
above limitation.
The amount of power delivered by the module is
defined as the voltage at the output terminals multiplied
by the output current. When using remote sense and
trim, the output voltage of the module can be
increased, which at the same output current would
increase the power output of the module. Care should
be taken to ensure that the maximum output power of
the module remains at or below the maximum rated
power.

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.
The trim resistor should be positioned close to the mod-
ule.
