    more specs/information needed.
    ac or dc? voltage in/voltage out/current out
    resistor divider, dc-dc converter,etc..

    "transformer-less" power supplies are a "banned" discussion topic on this board so tread lightly.

    Yes there are ways to do it. It is not a proper topic for this forum.
