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. Test Configurations All specifications are typical at nominal input, full load and 25° C unless otherwise stated.
