OZ968 - ETC

OZ968 SMBus Smart Inverter Controller

The OZ968 is a unique single-stage, highefficiency, CCFL backlight controller. It drives a zero-voltage-switching circuit and provides a near sinusoidal output voltage and current waveforms for a CCFL backlight. Typical operating frequency ranges from 30KHz to 100KHz. These advances drive the OZ968 beyond comparable conventional inverter designs with two pow.
