NXP’s High Frequency Tube Lamp (HF-TL) block diagram

NXP's family of fluorescent driver ICs consist of non-dimmable mainstream (UBA2015), dimmable (UBA2015A), and dimmable-boosted (UBA2016A) solutions. They support 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 requirements with respect to standards, 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).
