FUNCTIONAL DESCRIPTION  
Cord Compensation  
In some applications, the output voltage is increased  
with output current to compensate the potential  
voltage drop across output cable. The compensation  
is based on the high side feedback resistance.  
The compensation voltage is derived as:  
ÄVout = (VCSP-VCSN)*K  
Where K=3.03  
This voltage difference could be added on the  
reference or turning the (VCSP-VCSN) voltage into a  
sink current at FB pin to pull Vout higher than  
programmed voltage.  
The cord compensation loop should be very slow to  
avoid potential disturbance to the voltage loop. The  
voltage loop should be sufficiently stable on various  
cord compensation setting.
