Shenzhen Deming Microelectronics Co., Ltd. (hereinafter referred to as “Deming Microâ€) is a high-paying technology enterprise specializing in R&D, sales and trade of integrated circuits. The company is headquartered in Shenzhen, known as the "China Silicon Valley." Founded in July 2015, the company has focused on power management, LED lighting and LED display driver chip development. With perfect product quality, competitive sales price, accurate delivery time and good after-sales service, it is highly praised by the majority of merchants. As a small power supply brand of Demingwei, Zhangfei Power has shown its true power in the “worldwide†in just over two years, and has become a “hero†among many small and medium power power companies. Zhang Fei Power has set its clear goal since its inception, focusing on 3W, 5W low power power supply. Because Yang Fei, general manager of Zhangfei Power, always believes in "small power supply, there is also a big dream." Indeed, with its strict quality control, highly transparent sales price, fully automated production process, accurate delivery time and first-class after-sales service, Zhangfei Power has won the high recognition of the majority of lighting manufacturers in the shortest time. On the evening of December 22, at the 2017 Hi-Tech LED Awards Ceremony hosted by Gaogong LED and the exclusive title of Landwell, Zhang Fei Power relied on the new technology "for high-definition surveillance cameras" integrated light control dual-drive The light-free stroboscopic power supply won the annual innovation technology power category Golden Globe Award. Measuring value with reputation, taking the lead in innovation and winning the market with quality. Over the years, the selection of the high-tech LED Golden Globe Award has become the vane of industrial innovation and brand influence. In 2017, the high-tech LED Golden Globe Awards were selected as "one enterprise, one ingenuity is the "smith", and the "heart"". Since the opening of the registration channel in early November, more than 130 LED industry chains have been on the chain. Middle and lower reaches companies sign up for participation. Participating companies cover the entire industry chain of LED materials, equipment, chips, packaging, lighting. On the evening of December 22nd, the 2017 Gaogong LED Golden Globe Awards Ceremony was held in Shenzhen Baoan Dunxi International Hotel. On-site industry elites witnessed the LED industry's annual grand ceremony. The Golden Globe Awards Ceremony was exclusively named by Lande Vans, and the Golden Globe Awards Ceremony was also supported by Zhang Fei's power supply and excitation testing. Zhang Fei Power's "integrated" optically controlled dual-drive power supply integrates LED constant current drive power and constant voltage drive power on a single drive circuit board. Its main features and technical performance are small power supply, strong anti-interference ability, stable performance, low manufacturing cost, simple production and assembly, and saving assembly manpower. Regarding the constant current drive part, Zhangfei Power uses the ultra-high performance Mingwei SM7581 driver chip. SM7581 is a high-precision primary-side feedback LED isolated constant current driver chip newly introduced by Ming Microelectronics in 2017. It is suitable for 85V~265V full voltage input, and its constant current accuracy is within ±3%. It adopts professional detection and constant. Flow control technology eliminates the need for auxiliary winding detection and requires excellent peripheral performance for excellent constant current performance. At the same time, the chip operating current is extremely low, no need for auxiliary winding power supply, which greatly saves the power supply volume and reduces the power BOM cost. The SM7581 chip operates in the inductor current intermittent conduction mode, and the output current does not vary with the inductance and the LED operating voltage, achieving excellent load regulation. The SM7581 features multiple protection features including LED on and off protection, HVDD undervoltage protection, and chip temperature overtemperature regulation. Regarding the constant voltage drive part, Zhangfei Power adopts Taiwan Angbao driver chip. This chip adopts primary side feedback, constant voltage accuracy is less than 3%, built-in short circuit open circuit protection, over voltage, under voltage, over current protection, over temperature Protection, HVDD uses auxiliary winding power supply, and FB primary side voltage feedback makes the output voltage accurate and anti-interference ability. Regarding the control part, Zhangfei Power uses the imported Texas Instruments TI control chip and advanced photosensitive elements to make the photosensitive start-up and shutdown sensitivity high and the control performance more stable. In addition, some other core components such as transformers use high-quality PC40 thickened cores to ensure ultra-low operating temperatures with output currents up to 1A. Electrolytic capacitors use Aihua Electronics' 10,000-hour electrolytic capacitors for stable performance, high temperature resistance and long life.
