Based on NXP GreenChip™ technology, the new family of fluorescent driver ICs consist of non-dimmable mainstream (UBA2015
), dimmable (UBA2015A), and dimmable-boosted (UBA2016A
) solutions, supporting all common lamp types (T4, T5, T8, T12) and lamp configurations, including multi-lamp and multi-power solutions. The ICs drive a half-bridge circuit made of two MOSFETs with a supply voltage of up to 600 V and a PFC stage using one MOSFET. The new family of fluorescent driver ICs also features very low standby power levels (<100 mW), which further enhances energy efficiency. The many built-in protections support all standards, and meet industry requirements for reliability (including end-of-life protections) and performance. The ICs are available in both SO and DIP packages, supporting an easy and fast design-in. All products feature the adjustable current controlled preheat and accurate lamp current control (+/- 1 percent).

Cost-effective system solutions
Datapoint Research forecasts a shift from magnetic ballasts (57% in 2011) to electronic ballasts (75% in 2017) in the global fluorescent TL market, due to the higher efficiency enabled by IC-based electronic ballasts, which operate on higher switching frequencies, mainly for T4 and T5 lamp types.
“GreenChip technology lies at the heart of all our high-efficiency power and lighting ICs. In our latest fluorescent lamp driver family with boost functionality, we are setting a new benchmark for the high-end segment in commercial and professional-use general lighting applications. Our high voltage IC processes are optimized on performance and cost through continuous innovation and expertise, setting the industry standard for price and performance in smart power and lighting solutions,” said Ryan Zahn, general manager, lighting product line, NXP Semiconductors.
The UBA2016A, UBA2015 and UBA2015A fluorescent lamp driver IC family is in volume production. Samples and reference designs are available upon request via NXP.com
