| Abstract: | To adapt the development of LED lighting technology, the quality of the light, lumi- nous efficiency, reliability, and simplification of the design, based on introducing the function of SSL2108 driving chip, designs a new dimmable LED driving system based on SSL2108. The system mainly composed with four parts： input circuit, buck circuit, dimming control circuit, output cir- cuit. Experimental results show that the circuit can work properly and meet the designing goal. |
