Energy-efficient dimmable driver IC is world’s first to integrate PFC and boost functionality

February 17, 2012 | Paul Buckley | 222904141
NXP Semiconductors N.V. has unveiled what the company claims is the world’s first dimmable fluorescent lamp driver IC for High Frequency Tube Lamps (HF-TL) combining power factor correction (PFC) controller and ballast driver circuits. Using the boost function of the UBA2016A, high-end commercial-grade amalgam-based tube lamps will have a run-up time almost similar to mercury-based tube lamps.
The fully integrated dimming function, which is unique for this type of ballast controller IC, enables tube lamps to be dimmed gradually for a better sensory experience and for energy saving.

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).

Availability

The UBA2016A , UBA2015 and UBA2015A fluorescent lamp driver IC family is in volume production. Samples and reference designs are available upon request.
