Abstract:
According to an embodiment of the present invention, a power supply device includes a switching circuit, a detection circuit, a first comparator, a current source circuit, and a delay circuit. The switching circuit performs switching control of a power supply voltage. The detection circuit detects an output voltage from the switching circuit. The first comparator compares the voltage detected by the detection circuit with a first reference voltage which is set in advance. The current source circuit outputs a bias current which has correlation with the power supply voltage. The delay circuit receives the bias current from the current source circuit, and outputs, to the switching circuit, a delay time which corresponds to an increase time of the output voltage, by using the bias current in accordance with the result of comparison performed by the first comparator.

Claim (Index 1):
