How to use ICB1FL03G in alternative topologies is demonstrated in the subsequent figures. In Fig. 18 we see an
application for a single lamp with current mode preheating. Compared with Fig. 17 the difference is the connection
of the resonant capacitor in series with the filaments. In respect of operating behaviour the current mode
preheating cannot be designed with same variation of operating parameters: the preheating current is typically
lower and lamp voltage during preheating higher than in topologies with voltage mode preheating.
Figure 19 shows an application circuit of a ballast for a multi fluorescent lamp design in serial with voltage mode
preheating
