Abstract
A power inductor includes a core and winding. The winding has at least two portions, one made of pure copper and the other made of a low-TCR (temperature coefficient of resistance) alloy, wherein the alloy portion is used to form a current sensor. The two portions are joined to provide a unitary winding. The inductor can provide accurate current detection sensor while minimizing total resistance of the winding.
