As the load becomes light, the ON-period of the second transistor M2 increases. When the load RL turns from a heavy load to a light or no load, the overshoot suppressor 100 detects an increase in the ON-period of the second transistor M2, and then forcibly turns OFF the second transistor M2. Thus, an overshoot in the output voltage Vo is suppressed. Detecting an increase in the period for which the driving signal S2remains at high level H helps reduce malfunctioning due to noise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply circuit","description":"A power supply circuit has, for example, an overshoot suppressor 100, a control circuit 10, a first transistor M1, a second transistor M2, an inductor L, a capacitor C1, resistors R1 and R2, and an er","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9722587","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.
