13 The RT6190 is 4-Switch BuckBoost controller 13 The RT6190 is 4-Switch BuckBoost controller designed for converting input
14 voltage to output voltage that can be equal 14 voltage to output voltage that can be equal to, higher or lower than input
15 voltage. It operates with wide input voltage 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 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 b 17 used for the application like as BuckBoost bus supply, docking station and USB
18 power delivery product. 18 power delivery product.
