Abstract
A multiphase converter comprising a plurality of converter circuits, each converter circuit having series connected high and low side switches connected across a voltage bus with a common node provided therebetween, each of the common nodes connected through a respective inductor to an output node of the converter coupled to a load, the high and low side switches each being controlled by a control circuit to provide a desired output voltage at the output node, the control circuit including a first circuit for disabling and enabling at least one phase in response to a condition of the load, the circuit causing the high side switch to be turned on prior to the lower side switch when a disabled phase is enabled.
