OZ962G - ETC

OZ962G High-Efficiency Inverter Controller

The OZ962 is a unique high-efficiency, CCFL backlight controller. It generates symmetrical, near sinusoidal output voltage and current waveforms for driving a CCFL backlight. The OZ962 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 transf.
