ABSTRACT:
A fluorescent lamp driving circuit is provided. The fluorescent lamp driving circuit collects a pulse-width-modulation and a MOS switch in a single package. The pulse-width-modulation for driving multiple lamps only needs two pins to achieve feedback control and protection control. Thereby the pins required by the pulse-width-modulation are decreased substantially, and the electronic elements needed for feedback and protection control are also reduced, and the overall circuit design is simplified.
