ABSTRACT:
Circuits and methods to operate an arrangement of one or more charge pumps with two or more power supplies where each supply is able to vary over a range of voltages, and where any one supply can be of a higher or lower voltage than any of the others have been achieved. In a preferred embodiment the output of the arrangement of charge pumps is used to drive an electronic display. The strongest power supply available is selected and the arrangement of one or more charge pumps is reconfigured according to the value of the actual strongest supply voltage. In case of a change of a source of supply voltage the operation of the charge pumps during the short time required for reconfiguration. While the charge pump is running it can be suspended, reconfigured and released or restarted in the case of a change of supply source, or simply reconfigured on-the-fly without suspending in the case of a selected supply voltage change.
