Such a current compensation circuit accurately controls an average driving current regardless of change of an input voltage and an output voltage and is able to use a peak current mode control method to operate a light emitting diode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current compensation circuit and light apparatus comprising the same","description":"A current compensation circuit includes a current compensator configured to measure a compensation time in which a sensing voltage generated by a driving current passing through a driving switching el","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9780650","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.
