Product Summary

The OZ960S is a unique high-efficiency, CCFL backlight controller. It generates symmetrical, near sinusoidal output voltage and current waveforms for driving a CCFL backlight. The OZ960S operates in a single, constant frequency, pulse-width-modulation (PWM) mode. Typical operating frequency ranges between 30 KHz to 100 KHz, depending on the CCFL and the transformer’s characteristics. Operating in a PWM push-pull manner, the transformer in the OZ960S backlight inverter requires only one primary winding and one secondary winding, with the secondary winding requiring no fold-back treatment. The OZ960S is available in both 16-pin SOIC and TSSOP packages. It is specified over the commercial temperature range: 0 ℃ to +70 ℃.
