Abstract
The switching element is turned ON and OFF according to when the current flowing through the inductance element becomes equal to zero and according to an amplified error voltage between the output voltage and a target output voltage. More particularly, the OFF time of the switching element is calculated, and when the OFF time is less than a prescribed value, the ON time of the switching element is increased. Moreover, the amount by which the ON time of the switching element is increased is reduced if the error voltage if greater than a prescribed value.
