By using a ±0.5% tolerance trim resistor with a TC of
±25ppm, a set point tolerance of ±1.5% can be 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 trim resistor needed for a specific output
voltage.

Voltage Margining
Output voltage margining can be implemented in the
Naos Raptor 6A modules 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, Rmargin-down, from the Trim pin to output pin for
margining-down. Figure 51 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 Rmargin-up and Rmargin-down for a specific output
voltage and % margin. Please consult your local
Lineage Power technical representative for additional
details.
