description: |
Resistances of a voltage divider placed between Vout and the voltage
sense (Vsense) pin for the given channel (rail). It has two numbers
representing the resistances of the voltage divider provided as
<Rout Rtotal> which yields an adjusted Vout as
Vout_adj = Vout * Rtotal / Rout given the original Vout as reported
by the Vsense pin. Given a circuit configuration similar to the one
below, Rtotal = R1 + Rout.
