BP2318

BP2318 Dimmable Non-isolated Buck APFC LED Driver Description BP2318 is a high precision non-isolated buck APFC LED driver, specially designed for universal mains with constant current control. The driver with on-chip PFC circuit achieves high power factor, low THD and high efficiency。BP2318 operates in Critical Conduction Mode. Thanks for the Zero Current Switching, the switching loss is reduced and the inductor is fully utilized. BP2318 utilizes patented current detection, with few external components, it achieves high precision output current, excellent line regulation and load regulation, also the advanced line regulation from flex configuration of external components. BP2318 offers full of protection functions to improve the system reliability, including LED load open circuit protection, LED load short protection, VCC under voltage protection, Current Sense resistor open circuit protection, and over temperature protection. All the protection functions are auto-recovery. The sys...
