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

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.

Output Voltage Sequencing
The power module includes a sequencing feature, EZ-
SEQUENCE that enables users to implement various
types of output voltage sequencing in their applications.
This is accomplished via an additional sequencing pin.
When not using the sequencing feature, leave it
unconnected.
The voltage applied to the SEQ pin should be scaled
down by the same ratio as used to scale the output
voltage down to the reference voltage of the module.
This is accomplished by an external resistive divider
connected across the sequencing voltage before it is fed
to the SEQ pin as shown in Fig. 44.
