D340B Datasheet, PDF (1/9 Pages) List of Unclassifed Manufacturers – Electroluminescent Lamp Driver IC

General Description:
The Durel^ D340B is part of a family of highly integrated EL
drivers based on Durel’s patented three-port (3P) topology, which
offers built-in EMI shielding. This low-cost, regulated device is
well suited for backlighting timepieces and small liquid crystal
displays for portable electronic applications.
