Abstract

The invention relates to the technical field of circuits, in particular to a constant current circuit. The current adjustable constant current circuit comprises a constant current output circuit, a power supply module for supplying power and a control module provided with a control signal output end, the control module is connected with a voltage regulation unit through the control signal output end, a signal output end of the voltage regulation unit is connected with a signal processing module, and the signal processing module receives adjusting signals of the voltage regulation unit and outputs the adjusting signals to the constant current output circuit after analysis processing to achieve the regulation of the output current of the constant current output circuit. According to the constant current circuit, a current adjustment circuit is added on the basis of the existing circuit to obtain the current adjustable constant current circuit which is stable and not easy to produce malfunctions.

Description

Technical field [0001] The invention relates to the technical field of circuits, in particular to a constant current circuit. Background technique [0002] The constant current power supply method is an ideal power supply method for many loads. It can avoid the current change caused by the voltage change, so that the work of the load is stable, and it has a wide range of applications in many fields. In various constant current output devices, there are many ways to regulate current. However, in current current regulation, there is no ideal way to simply achieve stable output. Summary of the invention [0003] The purpose of the present invention is to provide a constant current circuit with adjustable current to solve the above technical problems. [0004] The technical problem solved by the present invention can be realized by the following technical solutions: [0005] A constant current circuit with adjustable current, comprising a constant current output circuit and a power sup...
