Abstract
A driver for electroluminescent (EL) lamps is an integrated circuit that includes a first transistor, a second transistor, and an inductor connected in series between the first transistor and the second transistor. The driver also includes at least four output circuits coupled to said inductor for separately driving at least four electroluminescent lamps. The driver further includes memory for storing data representing dimming levels and device addresses. Data is communicated to the driver through a serial interface that recognizes at least one standard protocol.
