DESCRIPTION
BP2876D could be used in the nonisolated buck mode constant current LED power which is suitable for 85Vac~265Vac voltage range, it is designed for flicker- free lightning field on purpose. BP2876D integrates a 500V power MOSFET. The operating current of the IC is very low. With very few external components count and no auxiliary winding., it can achieve excellent constant current performance, so the system cost and size are greatly reduced. There is high-precision current sense circuit inside the BP2876D, meanwhile the IC uses the patented constant current control, which achieves high-precision constant current output and great line voltage regulation. The IC works under inductor current critical conduction mode, so the output current is invariant with the inductance and LED voltage and it can achieve excellent load regulation. BP2876D has various protections, includes LED open circuit protection, LED short circuit protection, CS resistor short circuit protection, input undervoltage protection, over temperature regulation and thermal fold back.
