Abstract :
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.
