O2 Micro Unveils 3-Way LED Bulb Driver Controller

O2 (News - Alert) Micro International Limited recently added the patent pending OZ2083 3-Way LED Bulb Driver Controller with Power Factor Correction, to its General Lighting product portfolio.


LED-based, 3-way bulbs offer significant efficiency improvements as compared to their incandescent counterparts. They also provide longer operating life and eliminate the reliability problems that harm 3-way incandescent bulbs.

Officials said that the newly introduced O2 Micro's OZ2083 is a highly optimized controller for non-isolated Buck converter off-line applications. The device makes it easy and cost effective to design the complex driver circuitry required for a 3-way LED bulb.

Utilizing quasi-resonant technology, the OZ2083 3-Way LED Bulb Driver Controller with Power Factor Correction provides two detection inputs to support 3-way, 2-circuit sockets used within 3-way desk, table, and floor lamps to produce three levels of LED brightness in a low-medium-high configuration.

Manufacturers, with the help of the OZ2083, are able to easily and quickly develop drop-in LED bulb replacements for today's 3-way incandescent bulbs.

Featuring the highest level of integration, the device reduces the system-level-driver, bill of material cost and component count to industry-leading levels. Its external MOSFET offers the flexibility to support a range of application requirements.

The OZ2083 is available in a cost-effective 8-pin SOP package and supports universal 85V to 265V operation, which further enables one LED bulb to address the global marketplace.

Additionally, integrated power factor correction feature enables high power factor and low Total Harmonic (News - Alert) Distortion over a wide input voltage range, which successfully helps meet the residential and commercial requirements.

Earlier in April, TMC reported that O2Micro International (News - Alert) Limited, a major player in the design, development and marketing of high-performance integrated circuits and solutions, has launched its new and revamped corporate website at www.o2micro.com.
