<p>Provided are a control circuit for controlling an interleave power supply that is rarely affected by imbalance in parts and that is suited for mass production, and an interleave power supply provided with same. A clock generating unit generates a clock pulse with a prescribed frequency. A signal doubling unit generates a main-switch on-duration pulse signal on the basis of a main drive pulse signal that switching-drives a main switch of a main converter, and the clock pulse, and also generates a doubled duty-factor pulse signal that has doubled the duty factor compared to that of the main-switch on-duration pulse signal. An edge pulse generating unit generates a first edge pulse signal on the basis of the main drive pulse signal, and generates a second edge pulse signal on the basis of the doubled duty-factor pulse signal. A subordinate driving pulse signal generating unit generates a subordinate driving pulse signal such that the on-duration of the main switch and the on-duration of a subordinate switch become the same, on the basis of the first edge pulse signal and the second edge pulse signal.</p> |
