A replica signal is generated from the sense signal and transferred through a replica parasitic resistance circuit. A differential voltage is developed across the replica parasitic resistances and compared with a maximum limit voltage level. The maximum limit voltage level is indicates that a gain level of the switching DC-to-DC converter has decreased even though the duty cycle has increased. A duty cycle limit signal is generated and transferred to disable a switch in a switching circuit for limiting the duty cycle of the switching DC-to-DC converter, when the gain level has decreased such that the switching DC-to-DC converter does not enter a region where the gain of the switching DC-to-DC converter has a negative slope."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit and method for maximum duty cycle limitation in switching converters","description":"A switching DC-to-DC converter has an adaptive duty cycle limiting circuit with an inductor current sensor to generate a sense signal indicative of magnitude of the inductor current.
