FEATURES DESCRIPTIONS (CON.)
If the remote sense feature is not used to regulate the output
at the point of load, please connect SENSE(+) to Vo(+) and
SENSE(–) to Vo(–) at the module.
The output voltage can be increased by both the remote
sense and the trim; however, the maximum increase is the
larger of either the remote sense or the trim, not the sum of
both.
When using remote sense and trim, the output voltage
of the module is usually increased, which increases the
power output of the module with the same output
current.
Care should be taken to ensure that the maximum
output power does not exceed the maximum rated
power.
Output Voltage Adjustment (TRIM)
To increase or decrease the output voltage set point,
connect an external resistor between the TRIM pin and
either the SENSE(+) or SENSE(-). The TRIM pin
should be left open if this feature is not used.
Figure 16: Circuit configuration for trim-down (decrease
output voltage)
If the external resistor is connected between the TRIM
and SENSE (-) pins, the output voltage set point
decreases (Fig. 18). The external resistor value
required to obtain a percentage of output voltage
change % is defined as:

When using remote sense and trim, the output voltage

Care should be taken to ensure that the maximum
output power of the module remains at or below the
maximum rated power.
