The jitter control circuit causes a, for example, 8-bit counter that generates a modulation frequency to operate with, for example, 8 bits when 40 kHz≦fc and 7 bits when fc<40 kHz. In this way, even when the range of the EMI noise measurement frequency is extended to the lower frequency side, for example, to 25 kHz, the maximum reduction effect is maintained in the entire frequency range. Thus, the maximum EMI noise reduction effect is obtained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power supply control circuit and switching power supply","description":"A jitter control circuit, which reduces conducted EMI noise by giving jitter (frequency diffusion) to the operating frequency for driving a switching element, determines an operating frequency fc (e.g","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9673727","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.
