Abstract:This article describes an isolated boost DC / DC switching-mode power supply. The main topology is a push-pull circuit.UCC2808 is used in this paper. The experiments showed that the power supply has a very high voltage regulation and load regulation, highefficiency, low ripple, as well as a good circuit protection function.
