<p>A control circuit that controls an interleaved power supply, and an interleaved power supply including that control circuit, which are unlikely to be affected by a variation among components and are suitable for mass production, are provided. The clock generator generates a clock pulse having a predetermined frequency. The signal doubler generates a master switch on-interval pulse signal indicating information concerning an on-interval of the master switch based on the clock pulse and a master drive pulse signal that switch-drives the master switch of the master converter, and generates a doubled duty pulse signal having a duty that is double that of the master switch on-interval pulse signal. The edge pulse generator generates a first edge pulse signal based on the master drive pulse signal, and generates a second edge pulse signal based on the doubled duty pulse signal. The slave drive pulse signal generator generates, based on the first edge pulse signal and the second edge pulse signal, a slave drive pulse signal that switch-drives the slave switch so that an on-interval of the slave switch is identical to an on-interval of the master switch.</p> |
