一种新型自适应准恒定导通时间电流模式Buck变换器

There have been a variety of constant on-time (COT) controllers for dc power converter applications reported in recent years [1]–[5] . In this paper, a novel adaptive quasi-constant on-time current-mode control scheme is proposed and implemented in buck converters. While preserving the advantages of the conventional COT current-mode converters, this scheme allows fast transient response to step-lo...
