Output Voltage Programming
Figure 29. Circuit Configuration for programming
Output voltage using external voltage source.
Table 1 provides Rtrim values for some common
output voltages, while Table 2 provides values of
the external voltage source, Vtrim for same
common output voltages.
By using a 1% tolerance trim resistor, set point tolerance
of ±2% is achieved as specified in the electrical
specification. The POL Programming Tool, available at
www.lineagepower.com
helps determine the required external trim resistor
needed for a specific output voltage.

LOAD
The amount of power delivered by the module is defined
as the voltage at the output terminals multiplied by the
output current. When using the trim feature, 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 (P
Voltage Margining
Output voltage margining can be implemented in the
Austin SuperLynx
resistor, R
margining-up the output voltage and by connecting a
resistor, R
for margining-down. Figure 30 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at
under the Design Tools section, also calculates the
values of R
voltage and % margin. Please consult your local
Lineage Power technical representative for additional
details.
