Description
The FL-Controller ICB2FL02G is designed to control fluorescent lamp ballast including a
discontinuous mode Power Factor Correction (PFC), a lamp inverter control and a high voltage level
shift half-bridge driver with special detection thresholds for dimming applications.
The control concept covers requirements for T5 lamp ballasts for single and multi-lamp designs.
ICB2FL02G is based on the 2^nd Generation FL-Controller Technology, is easy to use and simply to
design in. Therefore a basis for a cost effective solution for fluorescent lamp ballasts of high reliability.
Figure 1 shows a typical application circuit of ballast for a single fluorescent T8 lamp with current
mode preheating.
