Functions :
OZ9933 is a high performance, cost-effective Cold Cathode Fluorescent Lamp (CCFL) controller designed to drive large-size LCD applications using 2. 4, or 6 CCFLs. It supports a full bridge, power conversion
This controller converts an unregulated DC voltage into a nearly sinusoidal lamp voltage and current waveforms. It supports full-bridge power conversion topology, while maintaining high efficiency operation. The OZ9933 offers a high level of integration, while maintaining flexibility and high efficiency operation that reduces external component heating, resulting in higher reliability and longer CCFL life. The proprietary design technique provides a simple, low-cost system solution.
