GENERAL DESCRIPTION
The OZ960 is a unique, high-efficiency, Cold Cathode Fluorescent Lamp (CCFL) backlight inverter controller that is designed for wide input
voltage inverter applications. Additionally, the OZ960 performs the lamp dimming function with an analog
voltage or low frequency Pulse Width Modulation (PWM) control.
Operating Principle: Operating in a zero-
voltage switching, full-bridge configuration, the inverter circuit achieves a very high efficiency power conversion. In addition, the transformer in the OZ960 does not requir...
