The high-side sensing type overcurrent protection portion sets the peak value threshold value to a value larger than the sum of the bottom value threshold value and a ripple component of inductor current during a period from start to end of a fixed on-time, and sets the peak value threshold value to a value equal to or smaller than the sum of the bottom value threshold value and the ripple component of the inductor current during a period after the fixed on-time elapses until at least the upper-side switch is turned off."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power supply device","description":"A switching power supply device is a fixed on-time with bottom detection type switching power supply device, including an on-time extending portion, a low-side sensing type overcurrent protection port","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819895","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.
