1. A voltage regulator module, comprising:
a circuit board unit comprising a top layer, a plurality of inner layers and a bottom layer;
at least one switch circuit disposed on the top layer;
a magnetic core assembly disposed on at least one of the plurality of inner layers and embedded in the circuit board unit, wherein the magnetic core assembly forms at least one magnetic loop; and
at least one first conductive member electrically connected with the at least one switch circuit for passing through a current of the at least one switch circuit, wherein the current passes through the at least one magnetic loop to form an inductor.
