High power-factor, constant current offline LED driver IC High Power-factor Constant current offline LED driver IC ADT6001 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 270V AC. It supports flyback topology and achieves very high power factor. It t LED Di i f t It d t t t l f ll it h d h th LED t

DESCRIPTION

It supports LED Dimming feature. It detects toggle of wall switch and changes the LED current 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℃.

FEATURES

  • 90V to 270V AC wide input range
  • High power factor architecture
  • High efficiency : up to 88% sinusoidal flyback
  • No need for any electrolytic capacitor
