Each POL regulator may have a respective phase in the current sharing configuration, and may transmit and receive information over the bus according to a bus communication protocol corresponding to the bus. The plurality of POL regulators may autonomously synchronize, to each other, a start time of their respective output voltage signal ramps by transmitting monitoring information to each other over the communication bus, while each of the POL regulators is ramping a duty cycle of a gate signal controlling a low-side field effect transistor of the output stage of the POL regulator according to a duty cycle of a gate signal controlling a high-side FET of the output stage of the POL regulator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method to properly ramp current sharing","description":"A distributed power management system may include a communication bus and a plurality of POL (point-of-load) regulators coupled to the communication bus, and configured in a current sharing arrangemen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487477","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.
