| 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. |
