Remote Sense Application Circuit
The Remote Sense function can regulate the voltage at the terminals (local sensing) or at the load.
(remote sensing). The maximum voltage compensation is 10% Vo, i.e.:
[Vo (+) to Vo (-)] – [Sense (+) to Sense (-)] < 10% Vo
If the Remote Sense function is not used, then the SENSE (+) should be connected to OUTPUT
(+)
and the SENSE(-) should be connected to OUTPUT(-) of the PXFmodule.
