Cxle8218 cxle8219 cxle8220 cxle8221 includes high-precision constant current primary side controller and power MOSFET, which is specially used for high-performance and small power LED lighting with simplified peripheral components. Cxle8218 cxle8219 cxle8220 cxle8221 works in the original edge detection and adjustment mode, and optocoupler and TL431 can be omitted. The patented technology of fast DMOS self power supply can save auxiliary winding and high voltage starting resistance of transformer. The chip provides a very comprehensive self recovery protection function, including cycle by cycle overcurrent protection, open-loop protection, over temperature protection and led short circuit protection. Built in high voltage start circuit and very low chip power consumption contribute to high efficiency. In the constant current mode, the current and output power can be adjusted by current and output power through RS resistance of CS pin, and the chip can meet the requirements of full voltage over certification and the chip can meet the requirements of full voltage over certification
