1. A power conversion system comprising:

  • a high-side circuit and a low-side circuit;

    a controller communicating with the high-side circuit and the low-side circuit;

    a first coupling circuit including a wire between the controller and the high-side circuit; and

    a second coupling circuit including a wire between the controller and the low-side circuit,wherein the high-side circuit includes;

    a high-side switch coupled between a first power supply terminal to which a first power supply voltage is supplied using a reference power supply voltage as a reference and a load drive terminal, the high-side switch supplying power to a load via the load drive terminal; and

    a high-side driver driving the high-side switch,wherein the low-side circuit includes;

    a low-side switch coupled between a reference power supply terminal to which the reference power supply voltage is supplied and the load drive terminal, the low-side switch supplying power to the load via the load drive terminal; and

    a low-side driver driving the low-side switch, andwherein the first coupling circuit includes a diode having an anode coupled to the wire from the controller and a cathode coupled to the wire from the high-side circuit.
