Driving circuit, switching control circuit, and switching device

A driving circuit (20) for driving a switching element in response to an input signal Vin, wherein the driving circuit (20) is provided with a positive power supply terminal (21) fed with a positive voltage Vcc, an input terminal (22) into which an input signal Vin is inputted, a ground terminal (23) connected to the source of the switching element (2), a first output terminal (25) capable of outputting a positive voltage Vcc in response to an input signal Vin, a current source circuit (10), and a second output terminal (26) connected to the current source circuit (10). The driving circuit (20) feeds a current Ig2, in which the positive voltage Vcc outputted from the first output terminal (25) is converted by a first impedance circuit (90), and a current Ig1 outputted from the current source circuit (10) through a second output terminal (26), to a gate, and thereby drives the switching element (2). 按照输入信号Vin驱动开关元件的驱动电路(20)，具备：被提供正电压Vcc的正电源端子(21)；被输入输入信号Vin的输入端子(22)；与开关元件(2)的源极连接的接地端子(23)；能够按照输入信号Vin输出正电压Vcc的第
