Semiconductor technology has changed the world, and semiconductor lighting technology will once again change our world. The LED lamp bead production process is constantly maturing, and the price of LED lamps is also decreasing year by year. At the same time, with the growth of the LED market, LEDs have gradually entered the field of residential home lighting. LED has the outstanding advantages of high efficiency, energy saving and long life. However, due to the high cost, the overall price of LED lamps remains high, which also hinders the popularity of LEDs. The result is that LEDs are only used for LCD backlights, decorative lighting and landscape lighting. And other high-end areas, but in the huge civilian home lighting market is still faltering. At present, it is in the critical period of LED popularization. Enterprises that can stand out in this round of LED popularization will surely become the leader of LED industry, and competitive solutions will be an indispensable factor for enterprises to break through.
The new SFL500/SFL520 series chips from Saiwei Technology have outstanding advantages in the LED driver field. The non-isolated Buck architecture makes the entire system more than 90% efficient and can be flexibly applied to 5W-30W systems. In order to simplify the development and design cost of customers, SFL500 integrates digital dimming and analog dimming functions. Few peripheral components reduce the development difficulty of the product, improve the reliability of the system, and reduce the system cost accordingly. Saiwei Technology also introduced the SFL520 optimized for TRIAC, which can easily develop a high-efficiency flicker-free thyristor (TRIAC) dimming solution thanks to the patented control algorithm.
Based on its leading design and process integration capabilities, Saiwei Technology has added 700V high-voltage rectifiers to the SFL500 series chips, enabling the chips to be directly powered from the AC, eliminating the need for power supply modules on the periphery of the chip. prominent. If the customer wants to reduce the power loss of the chip, the auxiliary winding can be added to the system, and the power supply of the chip is changed from high voltage to auxiliary winding, which can significantly reduce the power loss of the chip. The industry's first addition of frequency jitter design makes the SFL500/SFL520 series systems easy to face EMI challenges.
The SFL500/SFL520 series also integrates a number of protection features such as: VCC undervoltage protection (UVLO), VCC overvoltage protection, cycle-by-cycle overcurrent protection, GATE output clamp protection, LED open/short protection, and more.
The SFL500/SFL520 series are available in SOP8 and DIP8 packages.

Road Traffic Signs are graphical symbols that display traffic regulations and road information. They can make traffic regulations visually, concisely and concisely expressed. At the same time, they also express the content that is difficult to describe in words. They are used to manage traffic and indicate the direction of driving to ensure the smooth flow of roads and the safety of driving. Applicable to highways, urban roads and all special highways, with the nature of the law, vehicles, pedestrians must comply with.
