High efficiency 3.3-V/4-A synchronous flyback with hiccup protection reference design
Description
This flyback reference design is for an isolated 15-W low voltage rail. It features a LM5020—100-V wide input flyback controller. A synchronous secondary rectifier UCC24610 was used for high efficiency. It further enhances the LM5020 with hiccup protection by using a simply discrete circuitry. It is good for low voltage isolated supplies where high efficiency and hiccup protection are needed.
