The device includes a current detecting terminal and an overcurrent detecting circuit. The voltage proportional to the present current flowing through the primary side winding is applied to the current detecting terminal. The overcurrent detecting circuit compares a voltage corresponding to the voltage applied to the current detecting terminal with an upper limit current detecting voltage to detect an overcurrent. A correction current is applied to a correction resistor connected to the current detecting terminal for a shift in the voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power controlling semiconductor device, switched-mode power supply, and method of designing the device and power-supply","description":"A power controlling semiconductor device generates a drive pulse to turn on or off a switching device which applies an intermittent current to a primary side winding of a transformer in response to a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10491128","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.
