Feature Descriptions
Output Voltage Programming
The output voltage of the Austin MiniLynx
be programmed to any voltage from 0.75Vdc to
5.5Vdc by connecting a resistor (shown as Rtrim in
Figure 29) 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 MiniLynx
calculated as follows:
Figure 29. Circuit configuration to program
output voltage using an external resistor.
Table 1 provides Rtrim values required for some
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
section, helps determine the required external trim
resistor needed for a specific output voltage.
Voltage Margining
Output voltage margining can be implemented in the
Austin MiniLynx
R
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

section, also calculates the values of R
