The patent pending OZ9936 is a cost-effective CCFL (Cold Cathode Fluorescent Lamp) Power
Management controller designed for driving CCFLs in Liquid Crystal Display (LCD) applications.

The 0Z9936 provides two drive signals for most power conversion topologies, such as push-pull,
half-bridge, full-bridge or Class-D inverters while maintaining high-efficiency operation. The highly integrated controller provides current and voltage regulation, soft-start operation, over-voltage protection and an external enabling function while maintaining a high-degree of design flexibility. The application requires a minimum number of off-the-shelf components.[…]
