The secondary side includes a self-powered synchronous rectifier. The synchronous rectifier includes a synchronous rectifier transistor having at least a drain and a gate, a voltage regulator having at least an input that is coupled to the drain of the synchronous rectifier transistor, and an auxiliary transistor having at least a drain that is coupled to the drain of the synchronous rectifier transistor. The auxiliary transistor is on a same die as the synchronous rectifier transistor. The synchronous rectifier also includes a clamping device having at least an output that is coupled to the gate of the auxiliary transistor, and a gate driver circuit having at least: a power supply input that is coupled to the output of the voltage regulator, and an output that is coupled to a gate of the synchronous rectifier transistor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Self supply for synchronous rectifiers","description":"A power converter with an isolated topology may include a primary side and a secondary side.
