O2Micro Extended The Company's General Lighting Product Portfolio

O2Micro®International Limited, a global leader in the design, development and marketing of high-performance integrated circuits and solutions, today extended the Company's General Lighting product portfolio with the introduction of the OZ8022V LED Driver Controller.

"Our LED Driver Controller for the General Lighting Market solidifies our position as a leading solutions provider to this growing market," said Dr. Yung Lin, executive vice president, O2Micro. "By providing excellent operational flexibility, high efficiency, and ease of manufacturing in a compact form factor, the OZ8022V will help drive down the cost of retrofit LED lamps considerably."

About the OZ8022V LED Driver Controller

The OZ8022V supports universal 85V to 265V operation, enabling a single LED bulb to address the global marketplace, reducing SKUs and increasing operational efficiencies resulting from economy of scale. World-class LED current regulation and accuracy over the entire universal input range ensures consistent lumen output globally, regardless of varying line input conditions.

The OZ8022V supports non-isolated buck converter applications utilizing quasi-resonant conversion technology. High integration enables very low BOM-count and the absolute lowest cost at the system BOM level as well as compact design, accommodating space-constrained applications. The device is available in a very cost effective, small footprint, 6-pin SOT-23 package. Voltage-mode control simplifies circuit design.

Integrated power factor correction ensures high power factor (>0.9 over the universal 85V to 265V input range) and low THD (<20%) at full load, enabling bulbs that incorporate the OZ8022V to meet worldwide residential and commercial requirements and regulations, such as EPA Energy Star. Industry-leading efficiency of greater than 88% is maintained across the entire universal voltage range, reducing energy consumption and simplifying thermal management. During light load conditions, minimum off-time control maximizes operating efficiency. Low start-up current and operation current also maximize conversion efficiency.

The OZ8022V also features fast turn-on to meet end-user expectations. Integrated over-temperature, over-voltage, cycle-by-cycle current limiting, LED open circuit and LED short circuit protection with auto-recovery provide safe and reliable operation.

Target Applications

The OZ8022V is designed to address the high volume incandescent bulb replacement market, which includes PAR lamps, A bulbs and BR bulbs. An external MOSFET allows the OZ8022V to easily target a variety of power levels, meeting the needs of the 40W to 100W+ incandescent bulb equivalent replacement market.

Product Availability and Additional Information

The OZ8022V is available in a cost effective, small footprint, 6-pin SOT-23 package and is in high volume production now. Samples and evaluation boards are available now for qualified customers.
