It consists of a digital controller with load transient response approaching physical limitations of a given power stage that is suitable for low-power SMPS. In one aspect the invention is a method of utilizing a continuous-time digital signal processor (CT-DSP) for regulation of the operation of switch-mode power supplies. A CT-DSP can be used to instantaneously detect changes of voltage or current during transition periods and immediately perform control action that results in the fastest possible response. The invention may include current program mode controllers for SMPS where the input current is sensed as well as power factor correction rectifiers (PFC), where often input voltage, input current and output voltage are sensed. Upon sensing a deviation in the input voltage the CT-DSP is utilized to apply a switch-mode power operation whereby the controller switches between continuous-time and digital function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Continuous-time digital controller for high-frequency DC-DC converters","description":"The present invention is a voltage mode digital controller for low-power high-frequency dc-dc converters that has recovery time approaching physical limitations of a given power stage.
