description: |

  The MAX20730 is a fully integrated, highly efficient switching regulator

  with PMBus for applications operating from 4.5V to 16V and requiring

  up to 25A (max) load. This single-chip regulator provides extremely

  compact, high efficiency power-delivery solutions with high-precision

  output voltages and excellent transient response.

  vout-voltage-divider:

    description: |

      If voltage divider present at vout, the voltage at voltage sensor pin

      will be scaled. The properties will convert the raw reading to a more

      meaningful number if voltage divider present. It has two numbers,

      the first number is the output resistor, the second number is the total

      resistance. Therefore, the adjusted vout is equal to

      Vout = Vout * output_resistance / total resistance.
