Feature Descriptions
Output Voltage Programming (continued)
For example, to program the output voltage of the
Austin Lynx
follows:
Figure 31. Circuit configuration to program output
voltage using an external resistor.
Table 1 provides Rtrim values required for some
common output voltages.
By a using 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..

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 Lynx
R
margining-up the output voltage and by connecting a
resistor, R
for margining-down. Figure 32 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.
