Abstract: A voltage regulator module with a vertical layout structure includes a circuit board assembly, an electroplated region and a magnetic core assembly. The circuit board assembly includes a printed circuit board and at least one switch element. The printed circuit board includes a first surface, a second surface, a plurality of lateral surfaces, an accommodation space and a conductive structure. The switch element is disposed on the first surface. A conduction part is formed on the second surface. The conductive structure is perpendicular to the printed circuit board and disposed within the accommodation space. The electroplated region is formed on the corresponding lateral surface, arranged between the conduction part and the first surface, and electrically connected with the conduction part and the switch element. The magnetic core assembly is accommodated within the accommodation space. Consequently, an inductor is defined by the conductive structure and the magnetic core assembly collaboratively.

Abstract: A power converter module includes a multilayer printed circuit board, a switching device, a controlling device and a capacitor device. The switching device includes two switching circuit combinations. Each of the switching circuit combinations includes two switching circuits connected in parallel. Each of the switching circuits includes a switching unit. The controlling device is configured for outputting a first control signal and a second control signal to control the switching circuits of the first switching circuit combination and the switching circuits of the second switching circuit combination respectively. The first control signal and the second control signal are out of phase with each other. On a direction, the switching units of the first switching circuit combinations and the switching units of the second switching circuit combinations are alternately arranged, each of a plurality of capacitors of the capacitor device is neighboring to the two adjacent switching units.
