路。A DC input that has been rectified and smoothed from AC is applied to a series circuit of a switching transformer and a switching element made up of a field effect transistor, and the output of the transformer is rectified and smoothed to supply DC power to the load, and is turned on and off according to the output voltage control signal. In a switching type DC power supply in which the output of an IC-based pulse width control circuit that obtains a pulse with an off-ratio is used as a gate drive signal of the switching element, the slope of the rise and fall of the pulse output of the pulse width control circuit is determined by the slope of the rise and fall of the pulse output of the switching element. A switching type direct current that is adjusted by integrating the electrostatic charge between the gate and the source and the circuit resistance, and is equipped with a correction circuit that uses a diode to block the application of high voltage from the switching element to the pulse width control circuit side. Power supply control circuit.
