Original Abstract Submitted

An output node of a high-side driver circuit is coupled to the gate of a high-side transistor. The high-side driver circuit is structured to operate in a first mode in which the high-side driver circuit outputs a driving current with a first current amount during a first period from the transition of a high-side control signal HGCTL from the off level to the on level, and outputs the driving current with a second current amount that is smaller than the first current amount during a second period subsequent to the first period.
