Differential remote voltage sensing

11 Differential remote voltage sensing

L6713A

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.
