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.
FEATURES
• Supports wide-range voltage input
applications (8v to 20v)
• Built-in intelligence to manage ignition and
normal operation of CCFLs
• Reduces the number of components and
board size by 30% compared with
conventional designs
• 85% efficiency vs. typical 70% efficiency of
conventional designs
• Zero-voltage-switching full bridge topology
• Built-in internal open-lamp and over-voltage
protections
• Integrated burst mode control, and wide
dimming range (10% to 100%) with
integrated burst mode control
• Supports multiple CCFL lamps
• Simple and reliable 2-winding transformer
design
• Constant-frequency design eliminates
interference with LCDs
• Low stand-by power
