Figure 42. Circuit configuration for programming
output voltage using an external resistor.
Without an external resistor between Trim and
SIG_GND pins, the output of the module will be
0.6Vdc.To calculate the value of the trim resistor, Rtrim
for a desired output voltage, should be as per the
following equation:

Rtrim is the external resistor in k
Vo is the desired output voltage.
Table 1 provides Rtrim values required for some
common output voltages.

Digital Output Voltage Adjustment
Please see the Digital Feature Descriptions
section.
Remote Sense
The power module has a Remote Sense feature to
minimize the effects of distribution losses by regulating
the voltage at the SENSE pin. The voltage between
the SENSE pin and VOUT pin should not exceed 0.5V.
Analog Voltage Margining
Output voltage margining can be implemented in the
module by connecting a resistor, Rmargin-up, from the
Trim pin to the ground pin for margining-up the output
voltage and by connecting a resistor, Rmargin-down, from
the Trim pin to output pin for margining-down. Figure
43 shows the circuit configuration for output voltage
margining. The POL Programming Tool, available at
www.lineagepower.com under the Downloads section,
also calculates the values of Rmargin-up and Rmargin-down
for a specific output voltage and % margin. Please
consult your local Lineage Power technical
representative for additional details.
