Figure 25: Circuit configuration for trim-down (decrease
output voltage)
If the external resistor is connected between the TRIM
and RTN, the output voltage (Vout1) set point
decreases (Fig.25). Refer to the table below for the
external resistor values.

The output voltage can be increased by the trim pin,
When using 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 of
the module remains at or below the maximum rated
power.
