High power-factor, constant current offline LED driver IC High Power-factor Constant current offline LED driver IC ADT6001 ADT6001 DESCRIPTION The ADT6001 is a low power, high power-factor, constant current offline LED driver IC. It can operate with wide input voltage range from 90V to 270VAC. It supports flyback topology and achieves very high power factor. It supports t LED Di Dimming i feature. f t It detects d t t toggle t l off wall ll switch it h andd changes h the th LED currentt accordingly. It can replace then existing any light bulb with ADT6001 LED light bulb without any rewiring. It provides 3 dimming step, full power, 30%, and 15%. It also include over-temperature protection, it turns off the switching when its junction temperature exceeds 150℃.
