Description

OZ9972/72A are high performance, Pulse Width Modulation (PWM) controllers designed for large-size LCD TV applications requiring multiple lamps. They achieve high efficiency power conversion with minimal switching loss in a PWM, full-bridge, N-Channel MOSFET topology.
OZ9972/72A provide high drive capability, support a wide input range, and provide a constant, user-defined operating frequency.

FEATURES

• OZ9972:System synchronization for dimming and operation frequency
• Full-bridge topology
• Integrated high side N-MOSFET driver
• High drive capability and soft start function
• Constant operating frequency
• Built-in intelligence to manage lamp ignition and normal operation of CCFLs
• Open-lamp, over-voltage, over-current, and under-voltage lockout protection
• User-defined striking and shutdown delay timers
• Soft start function
