Embodiments enable dynamic switching of conversion ratios in reconfigurable power converters while under load without turning off the power converter circuitry or suspending switching of the charge pump power switches. Embodiments selectively increase the ON resistance, RON, for at least some power FETs in a power converter by actively controlling the driver voltage to the gates of the power FETs. During normal operation, the power FET driver voltage may be set to overdrive the FET gate to lower RON to a desired level that allows high current flow. For other scenarios, the power FET driver voltage may be reduced so as to increase RON while ON and thus impede current flow to provide protection against potentially damaging events."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic division ratio charge pump switching","description":"Circuits and methods to mitigate or eliminate potentially damaging events (e.g., damaging current spikes from in-rush current, charge transfer current, short circuits, etc.) in DC-DC power converters.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11942860","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.
