摘要：

In this paper an accurate loss model is proposed for synchronous DC-DC buck converters. The proposed method uses non-linear driver output stage model to accurately compute rise and fall times of MOSFET voltage and current waveforms to allow accurate calculation of switching loss. Transistor level simulations using Cadence Spectre circuit simulator and experimental results are used to demonstrate the accuracy of the driver model and the loss model at various input voltage, load current and switching frequency conditions.
