An integrated circuit device for a switching regulator, includes: a controller configured to generate a digital duty signal for a current mode control of the switching regulator based on an output voltage to be supplied from the switching regulator to a load circuit; and a switching pulse generating section configured to set a time ratio of a switching pulse signal for controlling turning-on and turning-off of a switching circuit which is provided in the switching regulator, based on the digital duty signal. The controller is a digital circuit which operates based on a master clock of the same frequency as a switching frequency of the switching circuit.
