| 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. |
