Abstract
A semiconductor apparatus that constitutes a step-down type switching regulator is disclosed. The semiconductor apparatus includes a switching transistor, an inductor, a transistor for rectification, and a transistor for synchronous rectification. The transistor for rectification is connected between a connecting point where the switching transistor and the inductor Lare connected and ground potential; and a gate of this transistor is connected to the connecting point. The transistor for synchronous rectification is connected parallel to the transistor for rectification. A control signal is provided to a gate of the transistor for synchronous rectification so that a switching operation that is opposite to an operation of the switching transistor may be performed. The transistor for synchronous rectification is arranged closer to the connecting point than the transistor for rectification.
