FUNCTIONAL DESCRIPTION

Cord Compensation

Cord Compensation increases the output voltage with

increased output current to compensate for the voltage

drop across the output connector and output cable.

The compensation voltage is derived as:

Δ

VOUT = RCS*IOUT*K

Where RCS is the current sense resistance, IOUT is the

load current, and K = 3.03
