摘要
The present invention provides a wirewound inductor of a switching power supply and a switching power supply with the wirewound inductor. The wirewound inductor comprises a magnetic core and a winding wound on the magnetic core. A buffering cushion is disposed between the magnetic core and the winding. The wirewound inductor provided by the present invention is provided with the buffering cushion between the magnetic core and the winding to absorb the dimension changes of the magnetic core caused by the magnetostriction phenomenon, and thus the relative positions of the components are maintained, the collision between the magnetic core and the winding can be prevented, and then the noise is reduced.
