Liquid crystal display (LCD) enclosures and cold cathode fluorescent lamps (CCFLs) used in notebook computer and portable electronics displays are becoming increasingly narrow, generating the need for a low profile CCFL power supply. Recent advances in single- and multi-layered piezoelectric ceramic transformers (PZT) have enabled the development of a new generation of efficient, size-reduced backlight converters. The UCC3975/6/7 family of 8-pin PZT controllers integrate the necessary circuitry for operating a PZT-based backlight supply using a flyback, half-bridge, or push-pull topology. The ...
