BP2328AJ

BP2328AJ Non-isolated Buck APFC Offline LED Driver Description The BP2328AJ is a high precision non-isolated buck driver with active PFC, specially designed for universal 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 BP2328AJ integrates a 600V power MOSFET. With few external components, the LED output current can be precisely controlled. The BP2328AJ utilizes patent pending 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 BP2328AJ 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...
