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

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.

The test results for this configuration are displayed in
Figure 17. For applications requiring voltage between
15 V and 24 V, consider using the JC050H, JC075H,
JC100H (24 V) trimmed down.
The voltage between the V
must not exceed 16.5 V. This limit includes any
increase in voltage due to remote-sense compensation
and output voltage set-point adjustment (trim). See
Figure 15.
If not using the trim feature, leave the TRIM pin open.
