基于 ATS1605的小功率恒流 LED 灯驱动电源

摘要

在传统反激变换器的基础上采用 ATS1605控制芯片设计了一款原边控制的 LED 灯驱动电源。文中介绍了其控制芯片和电路原理。实验验证了该设计的可行性和有效性。%In this article,based on conventional flyback converter,a primary-side controlled LED driver is designed u-sing ATS1605,and the controller and circuit theory are introduced.Experimental results demonstrate the feasibility and ef-fectiveness of the design.
