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 (P

).
Voltage Margining
Output voltage margining can be implemented in the
ATL010A0X43-SR module series by connecting a
resistor, R
margin-up
, from the Trim pin to the ground pin for
margining-up the output voltage and by connecting a
resistor, R
margin-down
, from the Trim pin to the Output pin
for margining-down. 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 Lineage
Power technical representative for additional details.
