Feature Descriptions
Output Voltage Programming
The output voltage of the Austin MicroLynx
can be programmed to any voltage from 0.75Vdc to
5.0Vdc by connecting a resistor (shown as Rtrim in
Figure 28) 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
calculated as follows:
Figure 28. Circuit configuration to program
output voltage using an external resistor
Austin MicroLynx
by applying a voltage between TRIM and GND pins
(Figure 29). The following equation can be used to
determine the value of Vtrim needed to obtain a
desired output voltage Vo:

Output voltage using external voltage source
Table 1 provides Rtrim values for most common
output voltages. Table 2 provides values of
external voltage source, Vtrim for various output
voltage.
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.
