High Power-factor
Constant current offline LED driver IC
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 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℃.
