Abstract
A inductorless method and apparatus for driving electroluminescent (EL) panels enables fabrication of an integrated circuit that provides a complete EL panel driver solution in one package. The high voltage required to drive the EL panel is generated by a plurality of charge pump circuits. A multi-stage charge pump may be used to provide a high voltage power supply that does not require an external capacitor to store energy for the power supply.
