Method and apparatus for converting DC input power to DC output power. In one embodiment, the apparatus comprises a first flyback circuit and a second flyback circuit, coupled in parallel, for providing DC-to-DC conversion; and a controller for (i) determining a first peak current, based on a predetermined peak current, for operating the first flyback circuit, (ii) determining a second peak current, based on the predetermined peak current, for operating the second flyback circuit, and (iii) operating the first and the second flyback circuits at switching frequencies dependent on the first and the second peak currents, respectively, to achieve timing synchronization for interleaved operation of the first and the second flyback circuits. |
