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.

Multiphase voltage regulator module with current amplification and absorption technique

This paper proposes a multi-phase voltage regulator module (VRM) based on the buck topology employing the current amplification and absorption technique. Main advantages of the proposed topology are the fast transient response and capability to keep constant the output voltage in case of severe load changes. The design, simulation and experimental results are presented to verify the proposed topology.

High-current clamp for fast-response load transitions of DC-DC converter

A new fast-response high-current clamp DC-DC converter circuit design is presented that will meet the requirements and features of the new generation of microprocessors and digital systems. The clamp in the proposed converter amplifies and absorbs the current in case of severe load changes and is able to produce high slew rate of load current and capability to keep constant the output voltage.

Forward type DC-DC converter with LC clamp for steep load transitions

In this paper presents a new fast-response DC-DC converter design that will meet the requirements and features of the new generation of microprocessors. A novel method of LC clamp is applied to a DC-DC converter, which is derived from a forward topology with self resetting facility. 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 verified by experiment of 12 V input and 1.8 V/12 A output.
