Feature Descriptions (continued)
Output Voltage Set-Point Adjustment
(Trim) (continued)
With an external resistor connected between the TRIM
and SENSE(+) pins (Radj-up), the output voltage set
The following equation determines the required exter-
nal-resistor value to obtain a percentage output voltage
change of
%.
The test results for this configuration are displayed in
Figure 16.
The voltage between the VO(+) and VO(–) terminals
must not exceed the minimum value of the output over-
voltage protection as indicated in the Feature Specifi-
cations table. This limit includes any increase in voltage
due to remote-sense compensation and output voltage
set-point adjustment (trim). See Figure 12.
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.
