最后从恒流精度、效率、成本3个方面综合分析了LED驱动电路的发展趋势。

Abstract

Taking specific LED driving IC for example

the principle

advantages

disadvantages and performance improvement measures of peak current control

average current control and single-stage single-switch no-isolated LED driving circuit are discussed. The conduction EMI peak and the average test results of LED driving circuit using the jitter frequency technology is given. The work waveform and efficiency test results of LED driving circuit of average current control based on IR2540 are also given. The principle of the pulsed constant current supply LED driving circuit is briefly introduced. At last the meta-analysis about the development trend of LED driving circuit is done from the three aspects of constant current precision

efficiency and cost.
