Frequency Domain Characterization of Voltage Mode Buck SMPS for Power Distribution Network

The paper introduces a power integrity (Pl) analysis for the efficient methodology to analyze the power distribution network of switching mode power supply (SMPS). In this paper, a generic frequency behavior for DC converter is proposed. Both time and frequency domain responses of a voltage-mode buck converter are described by the proposed model. A practical methodology demonstrates the effectiveness and the efficiency. The goal is to provide adequate performance for cost-effective and system solution and achieving on system-level success.
