In one embodiment, the control circuit includes a first control loop configured to control a one-shot timer to generate a control signal to turn on the main switch when the feedback voltage is below a first reference voltage and a minimum off-time duration has expired. The control circuit further includes a second control loop configured to control the one-shot timer to generate the control signal to turn on the main switch when the feedback voltage is below a second reference voltage and the minimum off-time duration has expired and a low-side current signal has a first state indicative of a light load condition at the output node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Constant on-time switching regulator implementing dual control loops","description":"A control circuit for a switching regulator implements constant on-time control scheme with synchronous rectification and applies dual control loops to improve light load efficiency and enhance transi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493047","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
