Cxle8266 is a switch regulated color temperature led driver chip, which is mainly used to coordinate with various isolated and non isolated LED drivers, and adjust the color temperature of LED lamps through wall switches. Cxle8266 has two-way 0V / 1 Ω power MOSFET built-in. The patented detection method is used to adjust the LED color temperature by continuously opening and closing the wall switch. Optional night light mode, and can adjust the brightness of night light through external resistance. Cxle8266 has high integration, only need few peripheral components, can realize the function of adjusting color temperature by switch, which greatly saves the system cost and volume. Cxle8266 has short circuit protection, over temperature protection and VCC under voltage protection functions
