Feature Descriptions (continued)
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

= V

).
Voltage Margining
Output voltage margining can be implemented in the Austin
MicroLynx
TM modules by connecting a resistor, R
margin-up
,
from Trim pin to ground pin for margining-up the output
voltage and by connecting a resistor, R
margin-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 R
margin-up
and R
margin-down
for a specific output voltage and % margin. Please consult
your local GE technical representative for additional details
