Abstract :
This paper presents a model for DC-DC converters that is used to study power management techniques like dynamic voltage and frequency scaling (DVFS) etc. It accurately predicts the behavior of DC-DC converters of varying topologies across output voltage and load current and predicts the relative benefits of different power management options down to low voltage and current levels.
