Feature Descriptions
Output Voltage Programming
The output voltage of the Austin SuperLynx
be programmed to any voltage from 0.75 Vdc to 3.63
Vdc by connecting a single resistor (shown as Rtrim in
Figure 30) between the TRIM and GND pins of the
module. Without an external resistor between TRIM pin
and the ground, the output voltage of the module is
0.7525 Vdc. To calculate the value of the resistor Rtrim
for a particular output voltage Vo, use the following
equation:
For example, to program the output voltage of the Austin
SuperLynx
follows:

LOAD
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.
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
R
margining-up the output voltage and by connecting a
resistor, R
for margining-down. Figure 31 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.
