基于事件驱动采样的数字电流模式控制中的恒定开/关时间混合调制

Ripple-based constant on-time and off-time control techniques can achieve fast step-down and step-up transient performance along with an improved light-load efficiency. However, they suffer from varying switching frequency at the steady state and often require a phase-locked loop for frequency regulation. This paper proposes a constant on/off-time hybrid modulation technique in a digitally current...
