Output Voltage Programming
The output voltage of the Austin SuperLynx II
be programmed to any voltage from 0.75 Vdc to 2.0 Vdc
by connecting a single resistor (shown as Rtrim in Figure
22) 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:

Table 1 provides Rtrim values required for some 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

variation with specific trim resistor values and tolerances.
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
