摘要
基于TOP247YN控制开关的离线反激式LED电源,采用单级功率因数校正(PFC)电路,产生一个12 V,1.67 A的输出,满足能源之星关于商业应用最低功率因数为0.9的要求,并达80%的效率。
The off-line flyback LED power supply based on TOP247YN control switch employs a single stage Power Factor Corrected（PFC） circuit. The supply generates a 12 V,1.67 A output and meets the Energy Star minimum power factor requirement of 0.9 for commercial with a high efficiency of 80%.
