OB3328/OB3328N High Performance CCFL Controller General Description The OB3328 is a unique, high-efficiency and highprecision Cold Cathode Fluorescent Lamp (CCFL) backlight co ntroller IC d edicated to full bridg e configuration. The controller i s de signed to drive single or multiple CCF Ls in Liquid Cryst al Display (LCD) applications. The OB332 8 convert s unre gulated DC input voltage to the pure sin usoidal voltage and cu rrent waveforms i n requi red freque ncy, to ignite and operate CCFL lamps. The OB332 8 provides a high deg ree of design flexibility by offering great program mability for key parameters which incl ude operating frequency, striking frequ ency, st riking time, bu rst dimming frequency, so ft-start time, and soft on/o ff time for burst dimming.
