    The AC1 and AC2 input Absolute Max rating is -0.8V to 20V. The OVP ckt will trip at 15V and limit voltage at about that point. The AC1 and AC2 inputs feed the internal full wave rectifier, output is at RECT. Voltage will be a diode drop negative and a diode drop above RECT voltage.

    What size coil are you looking for?
    Something the size of the one used on EVM or smaller?
