Abstract:
A multiphase direct current DC-DC regulator, the regulator including a DC output, the regulator comprising:a zero volt switch a DC output voltage means coupled to the zero volt switch and the DC output; a variable resonant circuit coupled to the DC output voltage means; a synchronous rectifier coupled to the DC output voltage means and the variable resonant circuit; and a sensing circuit coupled to the DC output and the variable resonant circuit, wherein the sensing circuit senses changes in a DC output voltage at the DC output, wherein if the sensing circuit senses an increase in the DC output voltage, then a resonant frequency of the regulator is decreased by the variable resonant circuit, wherein if the sensing circuit senses a decrease in the DC output voltage, then a resonant frequency of the regulator is increased by the variable resonant circuit.
