Abstract: An inductor module comprising: a first inductor, comprising a first inductor area; and a second inductor, comprising a second inductor area. A first overlapped area of the first inductor area and a second overlapped area of the second inductor area are overlapped. The second overlapped area comprises at least one first magnetic direction area and at least one second magnetic direction area. A ratio between a size of the first magnetic direction area and a size of the second magnetic direction area is a predetermined ratio such that a coupling effect between the first inductor and the second inductor is lower or equals to a predetermined value.
