0014 description: |
0015 The MAX20730 is a fully integrated, highly efficient switching regulator
0016 with PMBus for applications operating from 4.5V to 16V and requiring
0017 up to 25A (max) load. This single-chip regulator provides extremely
0018 compact, high efficiency power-delivery solutions with high-precision
0019 output voltages and excellent transient response.

0037 description: |
0038 If voltage divider present at vout, the voltage at voltage sensor pin
0039 will be scaled. The properties will convert the raw reading to a more
0040 meaningful number if voltage divider present. It has two numbers,
0041 the first number is the output resistor, the second number is the total
0042 resistance. Therefore, the adjusted vout is equal to
0043 Vout = Vout * output_resistance / total resistance.
