BP3218 High Efficiency TRIAC dimmable LED Driver Description The BP3218 is a high efficiency TRIAC dimmable LED driver. The device operates in critical conduction mode and is suitable for buck, buck-boost or fly-back LED lighting. The BP3218 utilizes patent pending MOSFET driving technique and current sensing method. The operating current of the IC is very low. With very few external components count, it can achieve excellent constant current performance, so the system cost and size are greatly reduced. The BP3218 offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC under voltage protection, CS resistor short circuit protection and thermal regulation function. The BP3218 is available in a SOP8 Package. Typical Application Features  TRIAC dimmable  Critical Conduction Mode Operation  Ultra Low Operating Current  ±5% LED Output Current Accuracy  LED Open Protec.
