+
+description:
+  The PF0900 is a power management integrated circuit (PMIC) optimized
+  for high performance i.MX9x based applications. It features five high
+  efficiency buck converters, three linear and one vaon regulators. It
+  provides low quiescent current in Standby and low power off Modes.
