UCC2973 BiCMOS 冷阴极荧光灯驱动器控制器

UCC2973 描述

Design goals for a Cold Cathode Fluorescent Lamp (CCFL) converter used in a notebook computer 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, improving overall system efficiency when compared to bipolar controllers requiring 5mA to 10mA of operating current. External parts count is minimized and system cost is reduced by integrating such features as a feedback controlled PWM driver stage, open lamp protection, startup delay and synchronization circuitry between the buck and push-pull stages
