Cxle8271 is a kind of LED driver chip with high efficiency supporting SCR dimming. The chip works in the inductive current critical continuous mode and is suitable for the LED driving power supply

Cxle8271 is a kind of LED driver chip with high efficiency supporting SCR dimming. The chip works in the inductive current critical continuous mode and is suitable for the LED driving power supply with buck, buck boost and fly back structures. Cxle8271 chip is internally integrated with 300V power switch. It adopts patented drive and current detection mode. The working current of the chip is very low. Only a few peripheral components are needed to achieve excellent constant current characteristics, which greatly saves the system cost and volume. Cxle8271 has multiple protection functions, including LED open circuit protection, led short circuit protection, CS resistance short circuit protection, undervoltage protection, chip temperature overheat regulation,
