Abstract
A coupled and integrated inductor provided in the present invention, includes a magnetic core and one or more conductive coil assembly embedded in the magnetic core; each conductive coil assembly comprises a first conductive coil and a second conductive coil coupled to the first conductive coil. The magnetic core is in close contact with both the first conductive coil and the second conductive coil; the first conductive coil and the second conductive coil pass through the magnetic core side by side, parallel and in close contact with each other, and the first conductive coil and the second conductive coil share a magnetic path. A trans-inductor voltage regulator provided, includes a circuit board and the coupled and integrated inductor electrically connected to the circuit board. The inductor has a coupling coefficient more than 92%, which improves the overall performance of the coupled and integrated inductor.
