GENERAL DESCRIPTION
The OZ965 is a single chip, high-efficiency, Cold Cathode Fluorescent Lamp (CCFL) backlight inverter controller whose primary function is to convert +5 volt DC power to approximately 600 VAC. Additionally, the OZ965 performs the lamp dimming function with an analog voltage or low frequency Pulse Width Modulation (PWM) control.

FEATURES
• Single-stage power conversion, requiring only a +5 V voltage source
• Reduces the number of components and board size by 30% compared with conventional design
• Supports both floating and grounded secondary designs
• 90% efficiency vs. typical 75% efficiency of conventional designs
• Internal open-lamp and short-circuit protections
• Wide dimming range
• Supports multiple CCFLs
• Simple and reliable 2-winding transformer design
• Eliminates leakage current when used in a floating secondary design
• Constant-frequency design eliminates interference with LCDs
