+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.
