Cxle8207, including high-precision constant current primary side controller and power MOSFET, is dedicated to high reliability and buck_ Small and medium power LED lighting with boost or flyback architecture and extremely precise peripheral components. The system can omit optocoupler and TL431. 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 over-current 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 RS resistance of CS pin, and the chip can meet the requirements of full voltage over certification.
