A second high-side driver is powered between a second bootstrap voltage (VBST2) and a second output voltage of a second high-side switch driven by the second high-side driver. A comparator is to detect VBST1 drop below a threshold value with respect to the first output voltage when the buck-boost converter is in boost mode. A leakage control circuit is to boost, using VBST2 as a voltage source, VBST1 each cycle of boost mode in which an output of the comparator is enabled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bootstrap voltage refresh for buck-boost converter","description":"An apparatus includes a first high-side driver of a buck-boost converter, the first high-side driver powered between a first bootstrap voltage (VBST1) and a first output voltage of a first high-side s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11522458","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.
