O2Micro® International Limited has developed the OZ8022M High Brightness Offline LED Driver Controller.

O2Micro's patented Free Dimming technology enables LED bulbs to dim using any on/off switch, thus eliminating cost, installation and compatibility problems associated with traditional incandescent dimmers. O2Micro's patented Free Dimming technology works with any on/off switch, including wall toggles, paddle switches, pull cords, rotary switches and other types of on/off switches commonly found on walls, extension cords and table/desk lamps.

According to the National Electrical Manufacturers Association (NEMA), there are over 4.4 billion medium, screw-based light sockets in the US. Yet, according to industry estimates, only 150 million incandescent dimmers represent an enormous, untapped market opportunity for O2Micro's Free Dimming technology, which is inherently simple and works with any non-dimming on/off switch.

Similar to O2Micro's OZ8022A and OZ8022B Free Dimming LED driver controllers, OZ8022M High Brightness Offline LED Driver Controller provides three-step dimming using any ordinary non-dimming on/off switch.

But instead of dimming from 100% to 60% to 20% with each flick of the wall switch, the OZ8022M dims from 100% to 40% to 2.5%, a low level night light mode. Consumers gain a built-in, free night-light while OEMs gain a value-added feature in a market sorely lacking in differentiation.

The OZ8022M supports universal 85V to 265V operation, enabling one LED bulb to address the global marketplace. High efficiency greater than 89% reduces energy consumption and thermal management complexity. Integrated over-temperature, over-voltage, cycle-by-cycle current limiting, and LED short circuit protection provides safe and reliable operation. Excellent LED current regulation ensures consistent lumen output, regardless of varying line input conditions.

The OZ8022M is available in a SOT-23-6 package and is pin compatible with the OZ8022A and OZ8022B. The OZ8022M is in high volume production now. Samples and evaluation boards are available now for qualified customers.
