Patent ID: 7945889

Claim:
A computer-implemented method for designing a voltage regulator module (VRM) using a computerized device comprising a storage, the VRM comprising a plurality of components, the method comprising: (a) receiving a plurality of design parameters and a component data for each of the components comprising the VRM, and storing the design parameters and the component data for each of the components into a component selection table of the storage; (b) calculating a work efficiency of the VRM based on the design parameters and the component data for each of the components, and storing the work efficiency into a power computation table of the storage; (c) simulating a derating of each of the components in the component selection table according to a corresponding rated stress of each of the components in the component selection table upon the condition that the work efficiency is greater than or equal to a predetermined work efficiency; (d) calculating a stress ratio of each of the components in the component selection table, and storing the stress ratio of each of the components into a component derating table of the storage; and (e) storing the component selection table, the power computation table, and the component derating table to form a desired VRM model if the stress ratio of each of the components in the component selection table meets a corresponding derating specification for each of the components in the component selection table; and (f) displaying the desired VRM model on a display that is electronically connected to the computerized device.
