| 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. |
