摘要
文章从经济实用角度出发,设计了一款基于AP3706的LED驱动电源。介绍了芯片特点和工作原理,采用了较少的元器件,设计了硬件电路,对电路在不同负载下进行测试,从测试结果看可以实现恒压、恒流输出,但是同时发现了电路中存在的电流不稳定的现象,并给出了优化方案。
This article from the perspective of economic and practical,Designed an LED drive power based on AP3706.Introduced the chip features and working principle,using fewer components,designed a hardware circuit,test the circuit under different loads,from the test results,constant voltage and constant current output can be realized.But at the same time,the phenomenon of current instability in the circuit was found,and proposed some optimization schemes.
