Abstract

This disclosure provides a transformer-inductor integrated device, a switching power supply, and a power supply device, and belongs to the field of power electronics technologies. The integrated device includes a magnetic core, a first conducting wire, and a second conducting wire. The magnetic core includes a bottom plate, a top plate, an inductor center post, a first side post, and a first transformer center post, where the inductor center post, the first side post, and the first transformer center post are arranged in sequence. A part of the first conducting wire is wound around the inductor center post and forms an inductor winding, and a part of the first conducting wire is wound around the first transformer center post and forms a first primary-side winding. The second conducting wire is wound around the first transformer center post and forms a first secondary-side winding. The first conducting wire is continuously wound around the inductor center post and the first transformer center post in an uninterrupted manner. In this way, the inductor winding and the first primary-side winding disclosed in this disclosure include a total of two pins, thereby reducing a quantity of pins by two compared with a discrete inductor and a discrete transformer in which an inductor winding and a first primary-side winding include a total of four pins.
