Cxle8419 is a constant current driver chip with three section switch dimming function. Suitable for 85vac ~ 265vacFull voltage input range of isolated LED lighting system dimming application

The CXLE8419 integrates the three section switch dimming function. The output current of LED can be operated at 100% and 50% through the switch of common switch
Switch between and 10%. Cxle8419's dimming mode is simple and convenient. It only needs ordinary switches without additional dimmers, which is simplified
LED lighting system design.
Cxle8419 adopts the control mode of original side feedback, through the information of original side feedback, high-precision LED constant current output can be realized. CXLE8419
Working in the quasi resonant switch mode, the power tube is in the state of zero current conduction. This effectively reduces the switching loss of the power tube and improves the system efficiency. Cxle8419 integrates line voltage compensation and load compensation functions, and the system has excellent line voltage regulation and load regulation. Cxle8419 working
Wide voltage range, suitable for 85vac ~ 265vac full voltage range AC input. At the same time, cxle8419 integrates multiple protection functions to ensure
The system is stable and reliable

Cxle8419 is a constant current driver chip with three section switch dimming function. Suitable for 85vac ~ 265vacFull voltage input range of isolated LED lighting system dimming application
