D356B Datasheet, PDF (1/12 Pages) List of Unclassifed Manufacturers – Electroluminescent Lamp Driver IC

General Description:
The Durel^Ò D356B 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 high efficiency device is well
suited for backlighting most timepieces and liquid crystal displays
for portable electronic applications.
