Cxle8264 is a LED switch temperature controller with internal integrated high-voltage power supply and two-way buck controller, which is suitable for 85vac ~ 265vac full range input voltage.
Cxle8264 chip detects the switch state through det pin to realize the switch state switching of cold, warm and mixed colors.
The cxle8264 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.
Cxle8264 has multiple protection functions, including LED open / short circuit protection, VCC under voltage protection, chip temperature overheat protection, etc.
