Feature Descriptions
Output Voltage Programming
The output voltage of the Austin MicroLynx
be programmed to any voltage from 0.75Vdc to 5.5Vdc
by connecting a resistor (shown as Rtrim in Figure 30)
between Trim and GND pins of the module. Without an
external resistor between 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
MicroLynx
follows:

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

Using 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
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 MicroLynx
resistor, R
margining-up the output voltage and by connecting a
resistor, R
Figure 31 shows the circuit configuration for output
voltage margining. The POL Programming Tool,
available at
Tools section, also calculates the values of R
