A common node in the power supply serially connects the control switch to the synchronous switch. The common node is further coupled to the inductor that supplies current to a load based on switching the control switch and the synchronous switch to respective ON/OFF and OFF/ON states. The voltage ramping circuit generates and controls ramping of a gate voltage of the control switch based at least in part on a magnitude of a feedback voltage received on a circuit path from the common node. The multi-stage ramping of a switch control voltage reduces one or more of the following: i) QRR losses, ii) switching losses, and/or iii) a dead time of the power supply."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit implementations reducing losses in a power supply","description":"A power supply circuit includes a control switch, a synchronous switch, an inductor, and a voltage ramping circuit.
