Embodiment Construction

[0014] An integrated circuit with built-in inductance, comprising a metal lead frame 1, a chip 2, an inductor 3 and a packaging material 4, and the metal lead frame 1, chip 2 and inductor 3 are all arranged inside the packaging material 4.

[0015] The inductance 3 is placed around the chip 2, and the plane surrounded by the coil of the inductance 3 and the plane on which the chip 2 is placed form any angle between 0° and 180°.

[0016] The number of inductance 3 is at least one; when there are multiple inductances 3 (as shown in the figure), the connection method of inductance 3 is series connection, parallel connection, both series connection and parallel connection, or independent connection with chip 2 .

[0017] The inductor 3 is placed along the periphery of the chip 2 (or the coil of the inductor 3 is placed around the chip 2).

[0018] The packaging material 4 is packaging plastic, silicon oxide and silicate, ceramics or any other insulating material.

Abstract

The invention discloses an integrated circuit with a built-in electrical inductor, which comprises a metal lead frame, a chip, the inductor and a packaging material, wherein the metal lead frame, the chip and the inductor are all arranged inside the packaging material. By packaging the inductor and the chip together, the invention saves both the circuit area and the installation procedures, and simultaneously improves the integration level and the performance of the system and reduces the total cost.

Description

Technical field: [0001] The invention relates to components and devices in electronic technology, and is an integrated circuit, specifically, an integrated circuit with built-in inductance. Background technique: [0002] Inductors are indispensable components in electronic technology. As electronic products continue to develop towards miniaturization and low power consumption, electronic circuits are simultaneously developing towards high density and miniaturization. Currently, inductors exist in the form of discrete components in electronic circuits, which not only occupy the area of ​​the circuit, but also require a separate installation step. In the integrated circuit, there is a large space available on the outer periphery of the chip and the packaging material. Packaging the inductor and the chip together not only saves the area of ​​the circuit, but also saves the steps of installation, and at the same time improves the system integration, improves performance, and re...
