OZ9966

OZ9966 FEATURES Full-bridge or dual-forwadr topology Integrated high side N-MOSFETdriver High drive capability and System synchor nization Dedicated pins forAnalog and LPWM dimming Selectable PWM dimming polarity Constant operating fer quency Built-in intelligence to manage lamp ignition and normal operation Open-lamp, ove-rvoltage, over-current, and under-voltage lockout protection User-def ned striking and shutdown delay timers Soft start function GENERAL DESCRIPTION The OZ9966 is a high performance controller designed for large-size LCDTV applications requiring multiple lamps. It achieves a high eff ciency power conversion with minimal switching loss using a full-bridge N-Channel MOSFETtopology. The OZ9966 is ideal for single-side drive or differential drive applications. OZ9966 allows selection of the Pulse Width Modulation (PWM) dimming polarity, and provides two dedicated pins for analog and PWM dimming control. APPLICATIONS APPLICATION DIAGRAM LCD TV 1 2 3 4 ...
