What is the equation for setting the TPS543C20RVFR’s output voltage? Does it depend on VSEL? Can you point me to where in the datasheet it walks you through how to do this?

Lauren,
Here are the relevant sections.
8.4.4 Voltage Reference | ||||||
8.4.16 RSP/RSN Remote Sense Function | ||||||
Datasheet is not as explicit as it could be.
Vout = VREF *( 1 + Rhs/Rls )
Rhs is high side feedback resistor
Rls is the low side feedback resistor
VREF is set in by Vsel
