Problems solved by technology

[0004] like figure 1 As shown, the traditional circuit board power supply module mainly includes electronic components such as a wirewound inductor 30, a power chip 31, a chip resistor 32, and a chip capacitor 33. The wirewound inductor 30 is welded on the circuit board 35 through the first pad 34. , the power chip 31, the chip resistor 32 and the chip capacitor 33 are all installed on the circuit board 35, so the traditional circuit board power module has the disadvantages of large volume and many passive components, which greatly limits its application range

Abstract

The invention discloses a power module of an integrated inductor, comprising a ferrite module, a bare chip and at least one metallic electrode plate, wherein the bare chip is arranged on the ferrite module, and is electrically connected with the ferrite module; and the at least one metallic electrode plate is fixed on the periphery of the ferrite module. The power module of the integrated inductor is small in volume, thereby satisfying the requirement of a highly-integrated system.

Description

technical field [0001] The invention relates to a power supply module, in particular to a power supply module with integrated inductor. Background technique [0002] In the application field of DC / DC (direct current / direct current) power supply, with the development of electronic technology, the size of electronic equipment is getting smaller and smaller, and the power density is getting higher and higher, which leads to the continuous miniaturization and integration of power modules. develop. The volume of the power module greatly limits the overall volume of the system, and it is increasingly difficult for traditional circuit board power modules to meet the requirements of highly integrated systems. [0003] Moreover, the installation cost of passive components is relatively high. Often in the power module, the cost of passive components is often greater than the cost of other components in the power module. The cost of these passive components will occupy the vast majori...
