Cxle8265 chip detects the switch state through det pin to realize the switch state of cold, warm and mixed color. The mixed color current can also realize different brightness by adjusting the external state of rdim1 / rdim2 pin.
The cxle8265 chip works in the inductive current critical mode, and the output current does not change with the inductance and the LED working voltage, thus achieving excellent linear / load regulation.
Cxle8265 has multiple protection functions, including LED open / short circuit protection, VCC under voltage protection, chip temperature overheat protection, etc.
