A Remote-Sense Compensation method is described which may be used to compensate for voltage drops between the sense points and the load that may be too significant to be ignored. Fig. 1 shows typical connections between a power supply and a load. The wiring resistance from the power supply to the connector is represented by R1 and R2. R3 and R4 represent the resistance from the connector to the sense points A and B. R5 and R6 represent the resistance between the sense points and the load. An assumption has been made here that the ideal pair of sense points, C and D, cannot be used due to packaging constraints and/or other considerations, such as R5 being a fuse. Since the sense points are at A and B, the voltage drops caused by R1 through R4 are of little consequence as long as the power supply can handle it.
