Abstract
A control circuit includes a first mode for thinning out pulses of a drive signal according to an input current, a hybrid mode combining pulse width control that controls a pulse width of the drive signal and intermittent control that thins out pulses of the drive signal, and a second mode for thinning out the pulses according to an output voltage. The control circuit selects the second mode when a duty ratio of the drive signal is a predetermined threshold or less, selects the hybrid mode when the duty ratio of the drive signal exceeds the predetermined threshold and the input voltage is a predetermined specified value or more, and selects the first mode when the duty ratio of the drive signal exceeds the predetermined threshold and the input voltage is less than the predetermined specified value.
