摘要

This paper proposes a digital constant on-time controlrnmethod for high switching frequency DC-DC buck converter,rnwhich eliminates the need for high resolution digital pulse-widthrnmodulator (DPWM) compared to constant frequency control.rnBoth simulation and experimental results demonstraternperformance improvement through the proposed off-timernprediction method in terms of the oscillation amplitude of thernoutput voltage.
