Abstract
A system includes an inductor and a first switch coupled between a first end of the inductor and a voltage supply node. The system also includes a second switch coupled between the first end of the inductor and a negative output supply node. The system also includes a third switch coupled between a second end of the inductor and a positive output supply node. The system also includes a fourth switch coupled between the second end of the inductor and a ground node. The system also includes a controller coupled to the first, second, third, and fourth switches. The controller is configured to provide an inductor charge mode, a positive boost mode, a negative boost mode, a first rest state involving the first switch, and a second rest state involving the fourth switch.
