BP2327A

BP2327A Non-isolated Buck APFC LED Driver Description The BP2327A 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. The BP2327A integrates a 650V power MOSFET, utilizes patent pending floating ground structure, and operates in Critical Conduction Mode. The switching loss is reduced and the inductor is fully utilized. The inductor current is sensed during the whole switching cycle and limited cycle by cycle. With few external components, it achieves high precision output current, excellent line regulation and load regulation. The BP2327A 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 au...
