Boost Converter Circuit

Abstract

A boost conversion circuit includes a first boost module, a first detection unit, a second boost module and a second detection unit. The first boost module has a first comparison control unit. The first detection unit is coupled to the first boost module, and the first detection unit adjusts a first input signal of the first comparison control unit according to a first signal of the first boost module. The second boost module is connected in parallel with the first boost module and has a second comparison control unit. The second detection unit is coupled to the second boost module, and the second detection unit adjusts a second input signal of the second comparison control unit according to a second signal of the second boost module. Through the cooperation of the first detection unit and the second detection unit, after the first boost module and the second boost module are connected in parallel, a larger current output can be obtained without increasing the inductance value of the inductor advantages, thereby reducing the thickness requirement of the electronic device provided with the boost conversion circuit.

Description

technical field [0001] A boost conversion circuit, especially a boost conversion circuit for a boost converter. Background technique [0002] Boost converters (boost converters) are commonly used in various electronic products to increase the input voltage to the operating voltage required by the electronic products so that the electronic products can operate normally. [0003] However, with the continuous development of electronic products in the direction of thinner and thinner, the internal space is more limited. The volume and height of the commonly used boost converter inductor will increase with the increase of the inductance value. When the boost converter needs a larger When the output current is higher, the required height of the inductor will increase, which is not conducive to the thinning of the electronic device. Contents of the invention [0004] The present invention provides a boost conversion circuit, including a first boost module, a first detection unit...
