一种用于片上Buck变换器的电流模式自适应导通时间控制器中的新型动态斜坡谷值控制

This paper proposes a novel dynamic ramp valley control in a current-mode adaptive on-time controller for the on-chip buck converter. It improves the system stability and reduces the output voltage under the load-dump. The proposed novel dynamic ramp valley control uses a sample and hold circuit, a comparator, and a ramp valley control to avoid the generation of an erroneous pulse signal while reg...
