摘要: 为适应LED照明技术发展对于光品质、发光效率、可靠性以及设计简单化的需要,在介绍SSL2108驱动芯片功能的基础上,设计了基于SSL2108的降压式可调光LED驱动系统。该系统包括输入电路、降压变换电路、调光控制电路、输出电路4大功能模块。实验结果证明该电路可以正常工作并达到设计要求。

关键词: SSL2108, LED驱动, 可控硅调光, 降压式拓扑

Abstract: To adapt the development of LED lighting technology,the quality of the light,luminous 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 circuit. Experimental results show that the circuit can work properly and meet the designing goal.

Key words: SSL2108, LED driving, controlled silicon dimming, buck topology
