Hi TI,
Regarding of TPS51220A feedback point(VFB) , datasheet figure 51 from Cout trace connection to R1 is normal routing layout guide.
The mode is local voltage sense, if it's connection mode from R1 point change to end device (remote device), Whether it's think of as a remote sense mode?
*Co is remote cap (close to end device); R1 is local part.
step1 : cut the local sensing trace of R1 connection Cout trace .
step2 : R1 connection to remote part(Co).

Hi有时候没有这么严格,具体看你需求。sense越靠近负载端,电压越接近设计值。
