implement a dimming function by frequency shift.

frequency can be made different from the pre–heating and the steady
state values. A frequency sweep between two defined values makes
this IC suitable for any series resonnant topologies.

yielding a 2% tolerance over the temperature range.
Strike
Main oscillator is current controlled, making it easy to set up by a
Filament pre–heating time control built–in.
The strike sequence is controllable by external passive components,
Dedicated internal comparator provides an easy lamp strike detection
Digital RESET pin provides a fast reset of the system (less than 10 s).
Adjustable dead time makes the product suitable for any snubber
Designed to be used with standard setting capacitors 470nF.
