Data Sheet
July 2, 2010 Austin MicroLynx TM SIP Non-isolated Power Modules:
3 – 5.5Vdc input; 0.75Vdc to 3.63Vdc Output; 5A output current
LINEAGE POWER 14
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
max
= 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 31 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 Lineage Power technical
representative for additional details
