CFL drivers enable energy-efficient bulbs

NXP Semiconductors has released two new generations of compact fluorescent lighting (CFL) light bulb drivers and controllers, based on its GreenChip technology. The UBA2027 family enables customers to develop CFL bulbs for energy saving lamps that provide smoother dimming capabilities to levels below 10 percent while the UBA221x family is designed for non-dimming CFL bulbs. Both solutions offer manufacturers quicker start times and improved reliability compared to current IC-based CFL solutions.

"We designed our CFL drivers to enable consumers to go green without the frustrations of conventional CFL bulbs. With governments all over the world prohibiting the production of incandescent light bulbs, a new energy-efficient lighting solution was required, one that meets consumer expectations of cost, reliability, lifetime and overall user experience," said John Croteau, senior VP and general manager, business lines high performance RF, power and lighting, NXP. "With 20 to 25 percent of the electricity produced in the world consumed in lighting applications, and over 5 billion energy saving bulbs to be sold in 2012 according to Datapoint Research, NXP's next generation of CFL lighting drivers break open the next 'killer application' for power management ICs. Backed by GreenChip technology, and NXP's ability to manufacture to scale, the economics are staggering."

NXP offers manufacturers solutions for dimmable and non-dimmable CFL drivers and controllers. Consumer perception of quality dimming starts at a dimming level of 10 percent light and traditional CFL lighting solutions can only be dimmed between 20 to 30 percent, which is not ideal. While today's NXP ICs already achieve the 10 percent dimming threshold, the new NXP-enabled lighting solutions achieve a level of deep dimming below 10 percent, making CFL lamps behave similar to incandescent bulbs. These CFL lamps will provide users with deep dimming performance; finally making energy-efficient lighting an option for mood lighting and advanced lighting designs.

GreenChip technology also accelerates the ramp up time, compared to standard CFL lamps, allowing the bulb to ignite faster. Consumers often complain about the reaction time between switching the light on to lamp ignitioncurrently an approximate delay of 0.5 to 1 second. NXP's CFL drivers have been demonstrated to improve the reaction time to within 100ms, therefore providing light immediately and meeting consumer expectations for instant light with no waiting and no frustrations.

The dimmable UBA2027 and non-dimmable UBA2211x families for CFL build on NXP's broad lighting portfolio. NXP IC-based solutions are fully supported by dedicated teams and tools. Design engineers benefit from seamless integration of CFL drivers into incandescent lamp form factors for easy migration to IC-based lighting solutions.
