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
