Remote Sense Application circuit

The Remote Sense function is used to compensate for the voltage drop incurred when the load is located physically

far away from the DC/DC converter providing its power. The Remote Sense pins are connected as close to the load as

possible. The DC/DC converter’s regulation specification is maintained across the points where the Remote Sense wires

are connected at the load. This will remove the effect of the voltage drop caused by the resistance of the wires used to

conduct the power from the DC/DC converter to the load. This is represented by R_CL1and R_CL2. With the use of Remote

Sense, the effects of R_CL1and R_CL2are eliminated.

If the Remote Sense function is not used, the +Sense has to be connected to +Vout and the –Sense has to be

connected to –Vout as close to the DC/DC converter as possible.
