ABSTRACT:
A multiphase direct current (DC) regulator using voltage mode control to provide a regulated voltage and provide current equalization between the phases. The regulator includes a voltage mode control circuit receiving an indication voltage level indicative of the amount of current supplied from the DC power source to an inductor of a first phase. The voltage mode control circuit providing a first control signal dependent upon the indication voltage level to a switching circuit that provides a switching signal to a switch. The switch controlling the amount of current from the DC power source supplied to a second inductor of a second phase according to the switching signal.
