The circuits and method use resonant energy capturing and filtering circuitry to provide an auxiliary power supply that may be used to power a controller of an SMPS. This circuitry includes a resonant circuit that recirculates and extracts energy at switch transitions of the SMPS. The circuitry required to implement the circuits and method is minimal, and provides advantages over techniques that require an additional power supply or that require an auxiliary winding in a transformer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resonant decoupled auxiliary supply for a switched-mode power supply controller","description":"Switched-mode power supply (SMPS) circuits and a method implemented within an SMPS are provided.
