Cxle8667 is a three section switch dimming single channel high voltage linear constant current LED driver chip. Cxle8667 adopts linear constant current technology and sets the driving current of LED lamp

Cxle8667 is a three section switch dimming single channel high voltage linear constant current LED driver chip. Cxle8667 adopts linear constant current technology and sets the driving current of LED lamp string through external resistance; it adopts two-stage structure and flexible configuration, which can meet the application requirements of 3-18 watt LED lamps; it adopts adaptive valley filling patent technology, which can improve the efficiency and linear adjustment rate of power system very well, with the highest driving rate of a single IC The power can be increased to 18W; cxle8667 supports switch dimming. When the power switch is quickly turned off and turned on, cxle8667 changes the driving current of LED light string in sequence, and the current proportion is 100% - 50% - 10%
