+description: |
+  The MAX20830 is a fully integrated step-down DC-DC switching regulator with
+  PMBus interface. It provides 2.7V to 16V input, 0.4V to 5.8V adjustable
+  output, and up to 30A output current. It allows monitoring of input/output
+  voltage, output current and temperature through the PMBus serial interface.
+  Datasheet:
