Abstract

This paper offers a comprehensive optimization approach for voltage regulator modules (VRMs). Minimal material cost is achieved while specifications for transient response, steady-state operation, and efficiency are treated as constraints with equal priority. The power stage and the controller are designed as a whole system by combining time-domain and frequency-domain models. Practical solutions consist of actual devices that can be implemented without further bench iteration. Optimization examples regarding multiphase VRMs are discussed to highlight the method´s flexibility and reliability. The optimization system showed potential to synthesize current VRM technology and provide useful insights.
