UCC1972 Overview
Design goals for a Cold Cathode Fluorescent Lamp (CCFL) converter used in a notebook puter or portable application include small size, high efficiency, and low cost. The UCC3972/3 CCFL controllers provide the necessary circuit blocks to implement a highly efficient CCFL backlight power supply in a small footprint 8 pin TSSOP package. The BiCMOS controllers typically consume less than 1mA of operating current,...
