Abstract

A voltage regulator module includes a circuit board, a metallic winding assembly, a switching circuit and a magnetic core assembly. The circuit board includes an accommodation space, a first surface and a second surface. The accommodation space is formed within the circuit board and in communication with a first opening and a second opening. The metallic winding assembly includes third opening. A projection region of the switching circuit and a projection region of the metallic winding assembly on the first surface are partially overlapped with each other. The magnetic core assembly includes an upper core, a lower core and a lateral leg. The upper core and the lower core are disposed on the circuit board. The lateral leg is penetrated through the first opening, the third opening and the second opening. An inductor is defined by the magnetic core assembly and the metallic winding assembly collaboratively.
