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. Figure 9 shows the
possible transitions between the states with their conditions.
