BP2356E

BP2356E Non-isolated Buck APFC LED Driver Description The BP2356E is a high precision non-isolated buck driver with active PFC, specially designed for high mains input offline constant current LED lighting. The driver with on-chip PFC circuit achieves high power factor and low THD. Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized. The BP2356E integrates a 500V power MOSFET. With few external components, the LED output current can be precisely controlled. The BP2356E utilizes patented floating ground structure. The inductor current is sensed during the whole switching cycle. So it achieves high precision output current control, and excellent line regulation and load regulation. The BP2356E utilizes patented start up technology with HV JFET. So it achieves fast start up, reduce count of external components, and realize smaller form factor. The BP2356E offers rich protection functions to improve the system reliability, i...
