In one embodiment, the control circuit includes a reference voltage selection circuit configured to select, based on a low-side current signal, a first reference voltage for standard load condition and a second reference voltage for light load condition as a selected reference voltage. The second reference voltage is greater than the first reference voltage. The control circuit further includes a control loop configured to generate a control signal to turn on the main switch when the feedback voltage is below the selected reference voltage and the minimum off-time duration has expired."},"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 light load control","description":"A control circuit for a switching regulator implements constant on-time control scheme with synchronous rectification and applies an integrated standard and light load control loop to improve light lo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493048","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.
