Abstract

The invention provides a power module applied to an intelligent terminal and a power module assembly structure. The power module comprises a substrate comprising a first surface and a second surface;the substrate is provided with a first conductive portion, an active element and a power type passive element; and the power type passive element is independently and completely arranged on the firstsurface of the substrate, wherein the maximum height of the power type passive element at the first surface of the substrate is larger than the sum of the maximum height of the element arranged on thesecond surface of the substrate and one half of the thickness of the substrate. The PCB utilization and the power density can be improved, and the power of the power module can be improve to a largerextent to meet the demands of functional diversification of intelligent terminals such as mobile phones and the like.

Description

technical field [0001] The invention relates to the technical field of electronic power, in particular to a power module and an assembly structure of the power module for an intelligent terminal. Background technique [0002] Considering the rapid development of today's cloud computing, network technology and various smart terminal markets, especially the smart terminal market, such as mobile phones, IPAD and other smart terminal markets are huge and growing at a high speed. [0003] In order to solve the problem of low conversion efficiency of the power supply system in the above application, a switching power supply solution is often adopted in the prior art. The switching power supply can greatly improve the conversion efficiency, but because of its complex circuit, the integration level is often not high, which limits the wide application of the switching power supply conversion scheme in this type of equipment. [0004] In order to solve the above problems, the solutio...
