Description BP2878K is a PWM dimmable high-precision low power factor buck for constant current LED driver. Internal the IC, it has PWM to analog dimming algorithm. It is designed for flicker-free and noiseless LED smart lighting applications. It is also optimized for linearity of dimming and output LED current accuracy. It is suitable for 85Vac~265Vac input voltage range. BP2878K utilizes MOSFET driving technique and current sensing method with very few external componentsg, it can achieve excellent constant current performance, so the system cost and size are greatly reduced. BP2878K has various protections, includes LED open circuit protection, LED short circuit protection, input under-voltage protection and over temperature regulation to enhance the system reliability.
