Feature Descriptions
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 module.
If not using the trim feature, leave the TRIM pin open.
With an external resistor between the TRIM and
SENSE(–) pins (R

obtain a percentage output voltage change of ý%.
The test results for this configuration are displayed in
Figure 23. This figure applies to all output voltages.

The following equation determines the required exter-
nal-resistor value to obtain a percentage output voltage
change of ý%.
Only trim up to 0.5 V maximum. See note above.
The test results for this configuration are displayed in
Figure 25. For applications requiring voltage between
15 V and 24 V, consider using the JW050H, JW075H,
JW100H, or JW150H (24 V) trimmed down.
The voltage between the V
must not exceed 15.5 V. This limit includes any
increase in voltage due to remote-sense compensation
and output voltage set-point adjustment (trim). See Fig-
ure 21.

and
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.
