All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a voltage control method according to an embodiment of the present invention. The method is applied to the terminal.
Specifically, the method is applicable to a terminal having a hardware configuration as shown in fig. 2. The terminal includes: a power supply 21, a power conversion chip 22, a load 23 and a detection control module 24. The power conversion chip 22 is connected to the power source 21 and the load 23, and the detection control module 24 is connected to the power conversion chip 22 and the load 23.
The method can comprise the following steps:
In this step, the voltage value of the input terminal of the load is detected in real time, so that once the voltage value of the input terminal of the load is detected to exceed the preset voltage range, the voltage value of the output terminal of the load can be adjusted in time to ensure the normal operation of the load.
And step 102, when the voltage value is out of a preset voltage range, adjusting the output voltage of the power conversion chip to enable the voltage value of the input end of the load to be within the preset voltage range, wherein the preset voltage range is larger than a first voltage value and smaller than a second voltage value.
In this step, the condition that the voltage value is outside the preset voltage range may specifically include: a case where the voltage value is greater than or equal to a first voltage value; or, the voltage value is less than or equal to the second voltage value.
It should be noted that the first voltage value and the second voltage value are voltage values at which the load normally operates.
Here, since the power conversion chip is connected to the load, that is, the output terminal of the power conversion chip is connected to the input terminal of the load, the output voltage of the power conversion chip, that is, the voltage of the input terminal of the load, is adjusted. That is to say, the purpose of indirectly adjusting the voltage of the input end of the load can be achieved by adjusting the output voltage of the power conversion chip, so that the normal work of the load is ensured.
According to the voltage control method provided by the embodiment of the invention, the voltage value of the input end of the load is detected; under the condition that this magnitude of voltage is outside presetting the voltage range, the output voltage of adjustment power conversion chip, the voltage that makes the input of load is in presetting the voltage range, it is greater than first magnitude of voltage and be less than the second magnitude of voltage to preset the voltage range, so, through above-mentioned software control, can be under the prerequisite of guaranteeing load operating voltage, reduce the requirement to power conversion chip output voltage precision and load transient response characteristic, reduce the control of the line impedance of walking of power conversion chip output to load input, greatly reduced electronic equipment's the actual design degree of difficulty.
Optionally, the first voltage value is a sum of a minimum operating voltage value of the load and a first voltage margin; the second voltage value is the difference between the maximum operating voltage of the load and a second voltage margin.

In addition, V is2＞V1，Va≥0，Vb≥0。Va、VbThe setting may be preset, or may be a default setting of the system, or may be set according to specific situations, and is not limited specifically here.
When V isaWhen equal to 0, V1Taking the value as the minimum working voltage value of the load; when V isbWhen equal to 0, V2The value is the maximum working voltage value of the load.

and increasing the output voltage of the power conversion chip under the condition that the voltage value is less than or equal to the first voltage value.
In this step, when the voltage value of the load is less than or equal to the first voltage value, it indicates that the voltage value of the load is lower and exceeds the preset voltage range, so that the purpose of indirectly increasing the voltage of the input end of the load is achieved by increasing the output voltage of the power conversion chip.
Based on the embodiment shown in fig. 1, as another optional implementation manner, step 102 may include:
and reducing the output voltage of the power conversion chip when the voltage value is greater than or equal to the second voltage value.
In this step, when the voltage value of the load is greater than or equal to the second voltage value, it indicates that the voltage value of the load is higher and exceeds the preset voltage range, so that the purpose of indirectly adjusting the voltage of the input end of the load is achieved by adjusting the output voltage of the power conversion chip down.

and adjusting the output voltage of the power conversion chip to a target voltage value, wherein the target voltage value is within the preset voltage range.
Here, the target voltage value may be set as the case may be. For example, for a load with a narrow upper and lower limit range of the operating voltage, preferably, the target voltage value is a typical value of the load during operation.
In order to reduce power consumption during load operation, it is preferable that the target voltage value is the first voltage value. I.e. close to the minimum operating voltage of the load.
Based on the embodiment shown in fig. 1, as another optional implementation manner, the adjusting the output voltage of the power conversion chip in step 102 may include:
and adjusting the output voltage of the power conversion chip according to a preset step length until the voltage value of the input end of the load is within the preset voltage range.
It should be noted that the present invention provides two adjustment manners of the output voltage of the power conversion chip, wherein when the voltage value is less than or equal to the first voltage value, the two adjustment manners may be adopted for the specific voltage adjustment manner for increasing the output voltage of the power conversion chip; when the voltage value is greater than or equal to the second voltage value, the specific voltage adjustment manner for reducing the output voltage of the power conversion chip may adopt the two manners described above.
It should be further noted that the voltage control method of the present invention can be executed by the detection control module 24 shown in fig. 2, and the terminal can further include an analog-to-digital conversion module, i.e., an ADC module, which can be embedded in the detection control module 24 and connected to the input pin of the load 23; the analog-to-digital conversion module may be also built in the load 23 and connected to the detection control module 24.
Here, the analog-to-digital conversion module is used to detect the voltage value at the input terminal of the load 23.
In particular, the minimum operating voltage V of the load 23 can be set when the terminal is turned onminMaximum operating voltage VmaxA first voltage margin VaAnd a second voltage margin VbThe write detect control module 24.
Note that, the reserved margin voltage, i.e., the first voltage margin VaAnd a second voltage margin VbThe voltage threshold of each load may be set and written into the detection control module 24.
The detection control module 24 detects the voltage at the input end of the load 23 in real time, and detects the voltage value V at the input end of the load 23 and the first voltage value Vmin+VaAnd a second voltage value Vmax+VbComparing; if V is less than or equal to Vmin+VaThen the voltage of the power conversion chip 22 is controlled to be increased; if V is greater than or equal to Vmax+VbThen the control turns down the voltage of the power conversion chip 22.
