	LED Driver


The AD100 IC is AC-DC Converter which controls DC output (DC250V, about 60/80/100mA) from AC input (220V±10%, 50/60Hz) by the Direct Power Control(DPC). This IC is designed to embed the function of inductors and transformers and to operate as a miniaturized very light rectifier which doesn’t need to use inductors as well as transformers.

8 lead SOP surface mount package with only a few other components save space and cost compare to alternative solutions.
The AC-input LED driver which use the AD100 IC provides commutated AC voltage to LED load in series, a method that is constant voltage/current. AD100 is Non-isolated.
AD100 minimize the stand-by power (under 0.1W at no load)
