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.
1. Full-bridge or dual-forward topology
2. Integrated high side N-MOSFETdriver
3. High drive capability and System synchronization
4. Dedicated pins forAnalog and LPWM dimming
5. Selectable PWM dimming polarity
6. Constant operating frequency
7. Built-in intelligence to manage lamp ignition and normal operation
8. Open-lamp, over-voltage, over-current, and under-voltage lockout protection
9. User-def ned striking and shutdown delay timers
10. Soft start function
