Voltage Margining  
Feature Descriptions (continued)  
Output voltage margining can be implemented in the  
12V Austin Lynx Programmable SMT modules by  
connecting a resistor, Rmargin-up, from Trim pin to ground  
pin for margining-up the output voltage and by  
connecting a resistor, Rmargin-down, from Trim pin to  
Output pin. Figure 30 shows the circuit configuration  
for output voltage margining. The POL Programming  
Tool, available at www.lineagepower.com under the  
Design Tools section, also calculates the values of  
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  
www.lineagepower.com under the Design 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 (Pmax = Vo,set x Io,max).

Remote Sense  
Q2  
The 12V Austin Lynx Programmable SMT power modules  
have a Remote Sense feature to minimize the effects of  
distribution losses by regulating the voltage at the  
Remote Sense and GND pins (See Figure 29). The  
voltage between the Sense pin and Vo pin must not  
exceed 0.5V. Although both the Remote Sense and the  
TRIM features can increase the output voltage Vo, the  
maximum increase is not the sum of both. The maximum  
Vo increase is the larger of either the Remote Sense or  
TRIM.

Q1  
GND  
The amount of power delivered by the module is defined  
as the output voltage multiplied by the output current (Vo  
x Io). When using Remote Sense and/or TRIM, the  
output voltage of the module can increase, which if the  
same output is maintained, increases the power output by  
the module. Make sure that the maximum output power  
of the module remains at or below the maximum rated  
power. When the Remote Sense feature is not being  
used, leave the Remote Sense pin unconnected.
