The new high performance microprocessors require the power supply to provide high current, fast transient response, and tight voltage regulation. Interleaved multiphase synchronous buck converters have recently been adopted in the industry to meet the requirements. To achieve current sharing among the multiple phases, a new control scheme is developed to combine current mode control with V2 control. It has the advantages of fast transient speed, inherent current shaking and easy compensation. In this paper, the principle and implementation of the new control is presented and the transient response is shown. The small signal model of multiphase converter with the new control is derived and applied in converter analysis and voltage loop compensation
