The hollow framework comprises two partition plates and a hollow pipe connecting the two partition plates, and the hollow pipe is sleeved on a middle column of the magnetic core. The coil comprises a secondary coil and a primary coil. The secondary coil and the primary coil are sequentially distributed along the radial direction of the hollow pipe, a first insulation layer is arranged between the secondary coil and the primary coil, and a second insulation layer is arranged between the partition plate and the secondary coil and between the partition plate and the primary coil respectively. A plurality of pins are arranged on the partition plate, and leading-out terminals of the secondary coil and the primary coil can be connected with the plurality of pins. The high-magnetic-permeability low-loss switching mode power supply transformer has the advantages of being high in magnetic flux density and magnetic permeability, low in loss, high in efficiency, small in power loss, not prone to heat in a work process, convenient and easy to install on a printed circuit board and the like.
