Part Number: TPS54618-Q1

for th TPS54618-Q1. How do I do remote sensing?

 Will the following have instability problem?

On the same PCB, about 6”~8” max from the POL.

    Michael,

    Generally I connect the top of the feedback divider after the last output capacitor.  However, I have successfully connected it as far away as 6 inches.  You do not need an additional 0 ohm resistor.  Keep the resistor divider close to the IC.  Make sure the FB trace is kept away from noise sources.
