Abstract
It is intended to provide a control circuit of power supply, a power supply and a control method thereof capable of achieving power saving in an integrated circuit and reducing a delay time of the integrated circuit. The control circuitof a power supplywhich outputs plural DC voltages VCC, VBGP, VBGN each having a different voltage value includes a voltage changing portion SWwhich detects an output current Irelating to a first DC voltage VCC which is one of the plural DC voltages and sets at least one DC voltage except the first DC voltage VCC based on the detected output current I, and the like.
