Embodiment 1

[0034] refer to figure 1 as shown, figure 1 A block diagram of an output current control circuit provided by the present invention.

[0035] The output current control circuit 7 includes: a power input terminal 1, a first filter module 2, a power management module 3, a second filter module 4, and a voltage regulation module 5; the power input terminal 1 is connected to the external power supply and the first The filter module 2 is electrically connected; the first filter module 2 is electrically connected to the power management module 3; the power management module 3 is also electrically connected to the second filter circuit and the voltage regulation module 5; The second filter circuit is also electrically connected to the voltage regulation module 5 .

[0036] Wherein, the above-mentioned external power supply is powered by 18650 or 26650 lithium battery. The above-mentioned first filter module 2 is used to filter the DC voltage of the external power supply, so that the...

Embodiment 2

[0048] Such as image 3 As shown, the embodiment of the present invention also provides an output current control system, the output current control system includes a drive circuit 10, a button and a power display circuit 9, a lighting device 8, an indicator light 12, a charging interface 11 and the The output current control circuit 7. The drive circuit 10 is electrically connected to the button and power display circuit 9 , the lighting device 8 , the output current control circuit 7 and the charging interface 11 . The indicator light 12 is electrically connected with the output current control circuit 7 .

[0049] Specifically, the above driving circuit 10 includes a controller, such as a single chip microcomputer. The key and power display circuit 9 includes a key circuit and a power display circuit. The key circuit can facilitate the user to control the output current control system. The power display circuit is used to inquire and display the power of the output curr...

Embodiment 3

[0052] Such as Figure 4 As shown, the embodiment of the present invention also provides an output current control method, the method includes the steps of:

[0053] Step 101. Obtain a preset current value, and the preset current value changes according to a preset ramp-down mode.

[0054] In the embodiment of the present invention, step 101 includes: reading the preset current value from a preset register, and the preset current value is stored in the preset register.

[0055] Specifically, the aforementioned preset current value is preset and stored in a register. The aforementioned preset ramp-down mode is a pre-set current ramp-down mode, for example, a current ramp-down process corresponding to weak light from a current corresponding to strong light at a certain current value. In this way, strong light can be slowly transitioned to low light to meet the optical needs of the human eye.

[0056] Step 102, adjust the output current according to the preset current value. ...

Description

technical field [0001] The invention belongs to the technical field of current control, and in particular relates to an output current control circuit, system and method. Background technique [0002] In the prior art, the circuit with output current control and management is easily limited by the input terminal, for example, the battery power at the input terminal is insufficient, and the use environment is harsh and interferes a lot. Once the flashlight is used in a harsh environment susceptible to interference, it will reduce the working efficiency of the driver or even cause the driver to fail to work normally. It can be seen that the existing output current control and management circuit has the problems of low working efficiency and poor stability. Contents of the invention [0003] The invention provides an output current control circuit, aiming at solving the problems of low working efficiency and poor stability of the existing output current control management ci...
