Supports Flyback (UCC3975), Half-Bridge  
(UCC3976), and Push-Pull (UCC3977)  
Topologies  
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  
choice of power topology depends on application  
requirements such as input voltage, lamp voltage,  
and PZT gain.
