The controller includes an oscillator and a monostable element, which are powered by the input voltage (Vin). The oscillator provides an oscillation signal (OSC) having a period T of a switching cycle of the switch. The monostable element (103) is controlled by the oscillation signal to determine a duration Tn of conduction of the switch, during which an increasing current (IL) flows through the inductor. The input impedance of the DC-DC converter increases, when the input voltage (Vin) drops below a first voltage threshold with a decreasing duty cycle d=Tn/T."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DC-DC converter with low start-up power and voltage","description":"A DC-DC converter (1) with low start-up power and voltage includes an inductor (3) connected to an input voltage source (2), a switch (11) connected to the inductor and controlled by a controller (10)","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742271","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.
