Description :

OZ9928 is a high performance, cost-effective 2-channel controller designed for large-size Cold Cathode Fluorescent Lamp (CCFL) or External Electrode Fluorescent Lamp (EEFL) Liquid Crystal Display Television (LCD TV) applications.

The controller provides six drive signals and is capable of driving full-bridge and Class-D topologies. The drive outputs are fixed phase when used for single-side or differential drive applications. Multiple OZ9928s can be synchronized to drive numer ous lamps.

The IC provides total system protection for differential drive and single-side drive applications.

Application Circuits


• Constant operating frequency

• 180 degree phase-shift PWM dimming

• Mixed-mode dimming control

• Integrated high side N-MOSFET driver

• High drive capability

• Selectable shutdown protection mode


• User-defi ned ignition and shutdown delay timers

Applications : LCD TV
