Abstract
An inverter for driving an EL lamp is tapped to provide voltage or current for driving one or more EL lamps, LEDs, and an LCD. In accordance with one aspect of the invention, one side of the pump inductor is tapped for a voltage that drives one or more LEDs and the LCD. In accordance with another aspect of the invention, the LEDs are in series with a storage capacitor and are driven by the current pulses to the storage capacitor.
