how to design an adapterfor 9V,100mA
adapter for what?? Where is this 9V 100 mA power coming from? and Going to??
You need to be a little more specific than that.....
input is the ac power supply line...
AC power supply line is:
120VAC single phase 60Hz
120VAC single phase 50Hz
110VAC single phase 50Hz
220VAC single phase 50Hz
240VAC single phase 60Hz
or something else?
There are many possible AC line voltages.
Just buy a wall adapter rated for 9V 100mA
