12description: |
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.
