Ming Chun Electronics Marketing Director Zhao Chunbo said in the lecture of Gaogong LED Tour Jiangmen Station that with the gradual introduction of national certification standards, the high power factor has gradually become an essential feature of medium and high power LED driver power supplies. Therefore, the high power factor stroboscopic drive scheme has become the new favorite of LED lighting.

According to Zhao Chunbo, the SM7650 introduced by Mingwei Electronics is a high-power factor, high-precision, high-efficiency primary-side feedback LED constant current driver chip for medium and large power. Applicable to 90Vac~264Vac input wide voltage range, system power factor is greater than 0.98, efficiency is higher than 85%, constant current accuracy is less than ±3%. At the same time, there is no power frequency flashing at the output, THD<10%.
In addition, SM7650 has passed 3C, UL, CE and other certification standards, with VDD undervoltage protection, GATE output clamp and output overvoltage, open circuit, short circuit and other protection functions, and can pass EFT, lightning, surge and other reliability tests. Zhao Chunbo said, "The product has been applied to LED downlights, LED waterproof power supplies, LED ceiling lamps and other fields." 
Studies have shown that the power frequency flashing (ie, stroboscopic) of LED lights can cause certain damage to the human eye. With the deepening of the global concept of health and environmental protection and the improvement of people's living standards, no strobe has become an essential attribute of LED lighting.
