摘要：
A power control device for performing switching control for an output voltage of a power supply device includes a signal generation circuit for comparing a difference between a value of the output voltage and a value of a first reference voltage with a value of a second reference voltage, and for stopping the switching control when a value of the difference is less than or equal to the value of the second reference voltage, and an adjuster circuit for adjusting the second reference voltage based on a ratio between a value of an input voltage and the value of the output voltage.
