具有占空比独立品质因数的恒定导通时间控制Buck变换器的小信号分析与设计

This article presents a frequency-domain analysis that models the behavior of Constant-on-Time (COT)-controlled buck converters in wide-input–output-range scenarios. Based on this analysis, a design strategy is proposed to enable robust control with a duty-cycle-independent quality factor, also known as a constant $Q$-value. A constant $Q$-value circuit based on the proposed strategy is then const...
