Feature Descriptions
Output Voltage Programming
The output voltage of the Austin SuperLynx
can be programmed to any voltage from 0.75Vdc to
5.5Vdc by connecting a resistor (shown as Rtrim in
Figure 29) between the Trim and GND pins of the
module. Without an external resistor between the
Trim and GND pins, the output of the module will be
0.7525Vdc. To calculate the value of the trim resistor,
Rtrim for a desired output voltage, use the following
equation:
Rtrim is the external resistor in Ω
Vo is the desired output voltage
For example, to program the output voltage of the
Austin SuperLynx
calculated as follows:

output voltage using an external resistor
Table 1 provides Rtrim values for most common
output voltages.

By using 1% tolerance trim resistor, set point
tolerance of ±2% is achieved as specified in the
electrical specification. The POL Programming Tool,
available at
Tools section, 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
resistor, R
for margining-up the output voltage and by connecting
a resistor, R
pin for margining-down. Figure 30 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at
www.lineagepower.com
section, also calculates the values of R
