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

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℃.
