D306A Datasheet, PDF (1/13 Pages) List of Unclassifed Manufacturers – Electroluminescent Lamp Driver IC

General Description
The Durel^® D306A is a high-power IC inverter intended for
driving EL lamps as large as 180 cm². The D306A IC is
equipped with many control functions, including: wave-
shaping^TM programmability for minimizing audible noise, and
features that allow for component cost-savings, precision
control of frequencies, and stability of lamp color over wide
temperature extremes.
