| 14 | description: | |
| 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. |
