BP2335JC Datasheet | BPS

Non-isolated Buck APFC LED Driver Description The BP2335JC 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 BP2335JC integrates a 550V power MOSFET. With few external ponents, the LED output current can be precisely controlled. The BP2335JC 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 BP2335JC utilizes patented start up technology with HV JFET. So it achieves fast start up, reduce count of external ponents, and realize smaller form factor. The BP2335JC offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC under voltage protection, CS resistor open circuit protection and cycle by cycle current limit. All the protection functions are auto-recovery. The system reliability is further improved by the thermal regulation function. The output current is reduced when the driver is over temperature.
