Feature Descriptions
Remote On/Off
If not using the remote on/off feature, do one of the
following:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to V

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 V01(+) or V02(–)
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 V01(+)
pins (R
increases (see Figure 5). The following equation
determines the required external-resistor value to
obtain a change in output voltage from V

and V02(–) pins (R

Feature Specifications table. This limit includes any
increase in voltage due to remote-sense compensation
and output voltage set-point adjustment (trim). See Fig-

Consult your Lineage Power Account Manager or
Application Engineer if the output voltage needs to be
increased 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 trim, the output volt-
age 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 maxi-
mum output power of the module remains at or below
the maximum rated power.
