Differential remote voltage sensing

Differential remote voltage sensing
The output voltage is sensed in fully-differential mode between the FB and FBG pin. The FB
pin has to be connected through a resistor to the regulation point while the FBG pin has to
be connected directly to the remote sense ground point.
In this way, the output voltage programmed is regulated between the remote sense point
compensating motherboard or connector losses.
Keeping the FB and FBG traces parallel and guarded by a power plane results in common
mode coupling for any picked-up noise.
