OZ9972, OZ9972ASN 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.

0Z9972, 0Z9972A provide high drive capability, support a wide input range, and provide a constant, user-defined operating frequency.


• 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
