Fast-response load regulation of DC-DC converter by inductor-switching high current path

This paper presents design considerations for a fast response voltage regulator module (VRM) for the worldwide-used microprocessors. The increasing steady state and dynamic requirements are very hard to meet with conventional design techniques due to parasitic elements of the circuit. To overcome the drawback with conventional design, a new topology of inductor switching technique is proposed. The design, simulation and experimental results are presented to verify the proposed topology.
