    TOP201YAI 3-Terminal TO-220 PWM switch Figure #7 in date sheet

    I would like to know what the specifications for the transformer in this data sheet is I would like to build one
    Also for figure number 8 as well
    Also for figure number 9 as well

    Here is the data sheet I know that this item has been disconnected but I can buy them surplus

    I have a mad scientist streak in me lately and want to be a little adventurous

    The reason is I have some ATX switching power supply that I have as spare parts from and wondering if I could use one for this purpose

    Or just use the standby circuit that is for this purpose but then I would have to reengineer the circuit to be able to use just this part of it
