15 The MAX20730 is a fully integrated, highly efficient switching regulator
16 with PMBus for applications operating from 4.5V to 16V and requiring
17 up to 25A (max) load. This single-chip regulator provides extremely
18 compact, high efficiency power-delivery solutions with high-precision
19 output voltages and excellent transient response.

37 description: |
38 If voltage divider present at vout, the voltage at voltage sensor pin
39 will be scaled. The properties will convert the raw reading to a more
40 meaningful number if voltage divider present. It has two numbers,
41 the first number is the output resistor, the second number is the total
42 resistance. Therefore, the adjusted vout is equal to
43 Vout = Vout * output_resistance / total resistance.
