This allows for stability in the feedback of Constant On-Time (COT) control for buck controllers when low Equivalent Series Resistance (ESR) capacitors are used as the output capacitor. The reference voltage is adjusted using features of a PWM cycle in a voltage mode without using external inductor current information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference voltage based equivalent series resistance (ESR) emulation for constant on-time (COT) control of buck regulators","description":"The present invention uses a reference voltage that varies within a Pulse Width Modulation (PWM) cycle to generate the PWM signal.
