... By inserting the filters (R4-C10; R5-C11) between the two secondary windings and the devices possible to guarantee a higher voltage on the input pin of the devices for longer time compared to the secondary signal. In this way it is possible to extend the use of the VK05CFL to all the power range eg.5W – 23W. ...

... Tube pre-heating By using the VK05CFL, the tube pre-heating can be done with the classical solution with PTC (see application schematic in figure 1) or with a more reliable low voltage network (see figure 5b). The pre- heating low voltage network allows to obtain an optimum pre-heating avoiding the overstress on the PTC thus improving the ballast reliability and the lamp life-time ...
