Feature Descriptions
Output Voltage Programming
The output voltage of the Austin MiniLynx
programmed to any voltage from 0.75 Vdc to 3.63 Vdc
by connecting a single resistor (shown as Rtrim in
Figure 32) 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 MiniLynx
is follows:
Figure 32. Circuit configuration to program output
voltage using an external resistor.
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
Tools 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
for margining-down. Figure 33 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at
under the Design Tools section, also calculates the
values of R
voltage and % margin. Please consult your local
Lineage Power technical representative for additional
details.
