  12 description: |
  13   The RT6190 is 4-Switch BuckBoost controller designed for converting input
  14   voltage to output voltage that can be equal to, higher or lower than input
  15   voltage. It operates with wide input voltage range from 4.5V to 36V, and
  16   the output voltage can be set from 3V to 36V by external FB pin. It's commonly
  17   used for the application like as BuckBoost bus supply, docking station and USB
  18   power delivery product.
