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 RCL1 and RCL2. With the use of Remote
Sense, the effects of RCL1 and RCL2 are 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.
