The application discloses an inductance assembly and an integrated power converter module. An inductance assembly is arranged on a bottom substrate, after integral plastic packaging, a signal electrical connecting piece is formed on the plastic packaging material through electroplating, and the signal electrical connector extends from the top surface of the inductance assembly to the side surface of the plastic packaging material and then extends to the bottom surface of the bottom substrate. The auxiliary winding is added to the second aspect to be coupled with the main winding to form a TLVR inductor for improving the dynamic performance of the VRM module. The VIN electrical connector is arranged between the main winding and the signal electrical connector, the middle portion of the VIN electrical connector is widened, and the transmission signal on the hopping signal interference signal electrical connector of the main winding is effectively avoided.

A coil component includes a coil, a magnetic core which is housed inside the coil, and a fixing unit which fixes the magnetic core to the coil such that the magnetic core is located within the coil in an axial direction. The coil is configured to include a winding wire which extends helically. The magnetic core has a high magnetic permeability and is housed in a central core portion which is inside the coil.
