Abstract: The present invention relates to a power module and a POL power module. The power module comprises an inductor and a main board; the inductor is disposed on the main board and includes an upper magnetic core, a PCB winding board, pins and a lower magnetic core; the PCB winding board is disposed between the upper magnetic core and the lower magnetic core; first ends of the pins are connected to the PCB winding board; and a second end, opposite to the first end, of at least one pin is extended and exceeds the bottom surface of the lower magnetic core, and is connected to the main board, so that a receiving space is formed between the bottom surface of the lower magnetic core and an upper surface of the main board. The power module of the application can provide at least two low-power independent outputs and can also provide high-power outputs in in-phase or interleaved parallel connection.

Abstract: The present disclosure discloses an inductor and a converter having the same. The inductor includes a magnetic core and a winding, the winding is provided within a window of the magnetic core, the winding includes a main body part and a sampling part, the main body part and the sampling part are connected in series, and a length ratio of the sampling part to the main body part is less than 2; wherein the main body part is formed of a low resistivity conductive material, the sampling part is formed of a low temperature coefficient conductive material, and a current flowing through the inductor is sampled across two ends of the sampling part. The inductor can obtain a current detection signal with high accuracy and low temperature drift with a compact structure, without increasing detection loss.
