The power supply circuit has a generating circuit that generates a clock signal having a constant period in a PWM control mode and a clock signal according to the output voltage in a PFM control mode. The control value of the control value generating circuit is changed so that averages of the feedback current before and after the control mode switching become equal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply circuit and control method thereof","description":"According to one embodiment, a power supply circuit includes a switching element to which a drive signal is supplied, a control value generating circuit that compares an output voltage and a reference","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9602000","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.
