LIS8611 isolation low PF (8-24W) first-class agent, hot debut

Two-winding primary side control driver characteristics Patented sampling and power supply technology for auxiliary winding Novel digital current loop control technology Integrated transformer sense compensation function Integrated leading edge conduction and blanking function Integrated frequency jitter function Ultra-low operating current () Ultra-wide output Voltage range Chip under-voltage and over-voltage protection function Cycle-by-cycle primary side peak current protection function Drive voltage clamp protection function Output open circuit, short-circuit protection function Over-temperature protection function Optimized constant current accuracy Optimized line voltage and load regulation Optimized current Temperature coefficient optimized system cost package overview is a control chip dedicated to constant current drive. By using proprietary primary-side constant current control technology, the system architecture is streamlined to the greatest extent. It not only eliminates the optocoupler and other feedback devices required for traditional secondary-side control, but also further eliminates the need for passive auxiliary windings, feedback resistors, and rectifier diodes for power supply in the traditional primary-side control architecture. devices, greatly reducing system costs. Due to the use of high-voltage direct power supply, the output voltage range of the system has been greatly broadened. The same drive system can drive multiple units in series, which facilitates the application of series models. The picture to the right shows a typical application of this chip. It also integrates complete protection functions, including cycle-by-cycle overcurrent protection for the input current, open circuit protection for the current detection pin, overtemperature protection, and open circuit and short circuit protection for the output. Application of spotlight driver, downlight driver, bulb driver, community lighting tube driver
