The CXLE86128 is a dimmable high precision primary-side regulation isolated flyback controller with single-stage Active PFC, specially designed for offline constant current LED lighting,The controller with on-chip PFC circuit operates in CCM (Critical Conduction Mode) to achieve high power factor and reduce the power MOSFET switching loss. The controller precisely control the LED current without secondary side sense and feedback circuit including opto-coupler. It uses source driver architecture and pending internal charging circuit for low primary side switching loss, ultra fast VDD start up and LED turn on. The CXLE86128 uses compensation method to achieve excellent line regulation, and it still can be tuned externally for flexibility.The controller also has outstanding load regulation for driving wide range of LED numbers. The CXLE86128 offers rich protection functions to improve the system reliability, including LED short circuit protection, LED open circuit protection, VDD over voltage protection, VDD under voltage protection, ISEN resistor short circuit protection, ISEN resistor open circuit protection, cycle-by-cycle current limit and die over-temperature protection
