title = "A DC-DC Converter with 30\% Reduced Undershoot Using Slew-Rate-Based Adaptive Frequency Control",
abstract = "This paper presents a buck converter architecture that dynamically adjusts its switching frequency based on the output voltage slew rate to enhance transient performance while maintaining high power efficiency. A compact analog circuit is used to detect rapid voltage changes and enables high-frequency switching only during fast load transients. This selective frequency scaling minimizes switching losses during steady-state conditions and improves responsiveness under dynamic loads. Simulation results demonstrate that the proposed technique reduces voltage undershoot by approximately 29\% compared to conventional fixed-frequency control schemes.",
