OZ965G-A1-0-TR - Brand New O2MICRO IC Chips
-
GENERAL DESCRIPTION
The OZ965 is a single chip, high-efficiency, Cold Cathode Fluorescent Lamp (CCFL) backlight
inverter controller whose primary function is to convert +5 volt DC power to approximately 600
VAC. Additionally, the OZ965 performs the lamp dimming function with an analog voltage or low
frequency Pulse Width Modulation (PWM) control.
Operating Principle:
The CCFL tube, transformer secondary, and capacitor form a resonant circuit. The OZ965 utilizes the low energy loss resonate mode principle to deliver a very high efficiency inverter. The OZ965 drives the transformer primary with a variable pulse width voltage directly from the +5v supply. The resultant primary drive current is alternately reversing with zero-voltage-switching.
Because of the transformer leakage inductance and the secondary resonant circuit, the secondary voltage and current are approximately sinusoidal. This sinusoid results in very little harmonic emi/rfi emissions.
The OZ965 operates at a single, constant frequency in a PWM mode. Typical operating frequency ranges between 30 KHz to 200 KHz, dependent upon the CCFL and transformer characteristics. Intelligent open-lamp protection provides design flexibility so various transformer models/manufacturers may be used. Its high driving capability allows the OZ965 to drive high power MOSFETs.The single stage design results in a low cost, reliable transformer without expensive, less reliable secondary fold-back treatment. The transformer does not require a more expensive center tapped primary.
The OZ965 is available in 16-pin SOP and TSSOP packages. It is specified over the commercial temperature range of 0°C to +70°C, and the industrial temperature range of -40°C to +85°C.FEATURES
