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 the TOP247YN control switch uses a single-stage power factor correction (PFC) circuit to produce a 12 V, 1.67 A output that meets ENERGY STAR requirements for commercial use with a minimum power factor of 0.9 and up to 80% efficiency.
