Abstract
An integrated transformer and an electronic device are provided. An integrated transformer includes at least one substrate defining a plurality of annular accommodating grooves. Each annular accommodating groove divides a corresponding substrate into a central part surrounded by the each annular accommodating groove and a peripheral part arranged around the each annular accommodating groove. The central parts and the peripheral parts, magnetic cores received in the annular accommodating grooves and conductive connectors assembled on the at least one substrate, and transmission wire layers on both sides of the at least one substrate cooperatively constitute a plurality of transformers and filters arranged according to preset arrangement manners. At least one of the transformers and at least one of the filters are electrically connected to form a group of electromagnetic assemblies, and any two groups of electromagnetic assemblies are not electrically connected with each other on the at least one substrate.
