The OZ968 is a unique single-stage, high efficiency, CCFL backlight controller. It drives a zero-voltage-switching circuit and provides a near sinusoidal output voltage and current wave forms for a CCFL backlight. Typical operating frequency ranges from 30KHz to 100KHz. These advances drive the OZ968 beyond comparable conventional inverter designs with two power conversion stages (one operates at a variable frequency, the other at a constant frequency).
