The output current is sensed by a current sense resistor R SENSE. As output current increases, the voltage drop across R SENSE will be limited to a reference voltage (V CS) to accomplish CC function. The def ault RSENSE is 27.27mΩ to get the typical CC point of 110% full output current. Cable Compensation The cable compensation can be calculated as below: VCABLE=IO* RSENSE *129.5k/RCABLE
