Dimmable driver IC integrates PFC and boost functionality
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).
