TPSM5D1806: TPSM5D1806 remote sense pin

Part Number: TPSM5D1806

Hello,

I am using TPSM5D1806 in single 12 A mode. For the design how would I route the remote sense signal. Should I route the remote sense signal in kelvin pair with FB1 signal between the bottom feedback resistor?

The RS- pin should be connected to the negative end of the output capacitors closest to the load. This will give the most accurate VOUT. See the diagram from the datasheet below.

the evm has rs- and fb connected to the vout (red marks). See the evm user guide for the pcb layout https://www.ti.com/lit/ug/sluuc66b/sluuc66b.pdf

Thanks,
Caleb
