Objective data sheet
7.4 Fluorescent lamp control
The IC incorporates all the regulation and control needed for the fluorescent lamp(s), such
as filament preheat, ignition frequency sweep, lamp voltage limitation, lamp current
control, start-up boost, dimming, end-of-life detection, overcurrent protection and hard
switching limiting.
In the UBA2016A/15/15A, 7 different operating states can be distinguished. In each state
the IC acts in a specific way, as described in the next paragraphs.
