The application discloses a full-integrated coupled oscillation DCDC converter with uniform phase interleaving, comprising a multiphase converter, an error amplifier and a multiphase control logic module; the multiphase converter is composed of a plurality of single-phase converters arranged in cascade, and the load output end of each single-phase converter is connected in parallel with the negative-phase input end of the error amplifier to output a voltage signal to the error amplifier; the error amplifier generates a control signal according to the output voltage of the multiphase converter and a reference voltage and outputs the control signal to the multiphase control logic module; the multiphase control logic module generates a corresponding pulse width modulation signal according to the control signal, which is input as an enable signal of the single-phase converter to control the activation number of the single-phase converter, so that the phases of the output voltage of the multiphase converter are uniformly interleaved. On the basis of retaining the grid charge recycling characteristic, the application realizes inherent even-phase interleaving, balanced current of each phase and balanced current of each inductor, and has a fast starting scheme, thereby improving the load transient performance.
