Abstract: A multi-phase transformer type DC-DC converter. In one embodiment, the multi-phase transformer type DC-DC converter includes a plurality of DC-DC converters comprising a plurality of transformers, respectively, wherein the plurality of DC-DC converters are coupled in parallel between an input and an output. A circuit is coupled to the plurality of DC-DC converters and configured to generate a plurality of clock signals for use by the plurality of DC-DC converters, respectively, wherein the plurality of clock signals are phase shifted with respect to each other.
