As a key component in the electronic system of power engineering, the power transformer IC has been widely used in various electronic products. It has key practical significance for ensuring the reliable operation of electronic products and achieving energy saving and consumption reduction. In recent years, the power transformer IC manufacturing industry has maintained a high-aspect ratio passion for project investment. On the one hand, due to the continuous influx of new entrants and increased market demand, some companies in the manufacturing industry with strong overall strength expect to obtain collaborative economic benefits based on extensive corporate mergers and acquisitions to create a company around the city; on the other hand, with new Energy vehicles and other segmented manufacturing industries continue to develop rapidly, and the indoor space in the sales market of the manufacturing industry is steadily increasing. Many companies look forward to choosing this main use according to methods such as project investment and corporate mergers and acquisitions to obtain core competitiveness.
Although China’s power transformer IC manufacturing industry has many participants, it is still very different from European and American manufacturers in terms of the scale of the industrial chain and the competitiveness of high-end products; if mainland Chinese manufacturers want to join the leading cluster, they must first respond A long-term battle that requires both money and talents. Shenzhen China UnionPay Automation Technology Co., Ltd. has 20 years of technical expertise in power transformer IC technology, strong overall assets and first-class service quality. Welcome to talk.
China UnionPay Automation Technology’s new product development and production has produced a U6235 power transformer IC with VDD bottom voltage self-powered system function, and the transformer can remove the auxiliary winding. U6235 power transformer IC is a high-performance primary-side controlled output power power switch, which can show the output characteristics of high-precision constant current source and constant current power source, especially suitable for the application of low output power line charging head and LED Christmas lights.
U6235 power transformer IC advantages:
1. With VDD bottom voltage self-powered system function, the transformer can remove auxiliary winding
2. Has a quick opening effect
3. Start with LineBOP function
4. Integrated 800V high voltage output power BJT
5.±5% constant current power supply, constant current source precision
6. Multi-mode primary side manipulation method
7. No sound at work
8. Adjustable line loss compensation
9. Constant current power compensation with integrated phase voltage and load working voltage
10. Integrated and sound maintenance function:
11. Overcurrent protection (SLP)
12. Over temperature protection (OTP)
13. Cycle-by-cycle time overcurrent protection maintenance (OCP)
14.FB over voltage protection (FBOVP)
15. Start phase voltage undervoltage protection (LineBOP)
16.VDD over voltage protection
17. Package type SOP-7
U6235 power transformer IC contains VDD bottom voltage self-powered system control module, which is suitable for PSR architecture with two windings. It also has a fast turn-on function, allowing VDD to choose a large space (22uF or 30uF) electrolytic capacitor, which promotes the switching power supply can be integrated into ultra-low temperature applications such as LED Christmas lights. U6235 also has a phase voltage undervoltage protection function at startup, which can prevent the PSR from finding an abnormal operating state when the phase voltage is too low.
