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