Abstract
An apparatus includes a reconfigurable charge pump including charge pump cells configurable into multiple different arrangements. The apparatus includes a control device configured to select a first arrangement of the charge pump cells from the multiple different arrangements based, at least in part, on an input voltage received by the reconfigurable charge pump and requested parameters of a drive signal for a touch screen panel. The reconfigurable charge pump can boost the input voltage based, at least in part, on the first arrangement of the charge pump cells. The control device can generate the drive signal according to the requested parameters based on the boosted input voltage.
