Abstract
A driver circuit is configured to operate the switching elements using constant ON-time control. A monitoring circuit generates a first control signal indicating whether the DC/DC converter is in a steady state or in an abnormal state. An ON-timer circuit generates a second control signal based on the first control signal, and send the second control signal to the driver circuit, the second control signal provided for terminating a partial interval of each switching cycle of the switching elements, the partial interval being defined such that energy is stored to the inductor in the partial interval. The ON-timer circuit generates the control signal using a first reference voltage varying according to a duty ratio of the switching elements, when the DC/DC converter is in the steady state. The ON-timer circuit generates the control signal using a second reference voltage being fixed, when the DC/DC converter is in the abnormal state.
