A multi-phase DC-DC converter is described with a number N (N > 1) of parallel-connected single converters serving as phases, which are connected to a common input terminal and a common output terminal, to which a decoupling capacitor (Ci', Co') is connected in each case, wherein a measurement signal coupling circuit is connected to the input and / or the output terminal, each of which is connected to a circuit between the input and / or output terminal.The first series circuit, consisting of a first capacitor (Ci, Co) and a first resistor (Ri, Ro), is connected to the output terminal and a reference potential terminal. A second series circuit, consisting of a second capacitor and a second resistor (Rdet), is connected to the center tap of the first series circuit. The terminal of the second resistor (Rdet) not connected to the second capacitor (Cdet) is connected via a third resistor (Roff) to an auxiliary voltage source (Voff) and via a reverse-biased diode (Ddet) to the reference potential, forming the input or output measurement terminal (RIPPLE_IN or RIPPLE_OUT).

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.
