The advances of new LSI technology impose a new challenge for providing high quality power to new generation microprocessors. The challenges of the voltage regulator module come from the requirements of very low voltage and high current to ensure the low power consumption and high clock speed. In this paper presents a new fast-response multi-phase DC-DC converter design that will meet the requirements and features of the new generation of microprocessors. A novel method of low inductance clamp is applied to a multi-phase DC-DC converter, which is derived from a buck topology. It produces a high slew rate of load current and keeps output voltage constant in case of severe load changes. The design of the concept is implemented by experiment of 12V input and 3.3V/30A output.
