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 application. Non-conflicting ones of the following embodiments may be arbitrarily combined.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a power supply regulator according to a first embodiment of the present application, in which a power supply is externally connected to the power supply regulator 1 for regulating and outputting a corresponding voltage signal to supply power to a load, and the power supply regulator 1 includes: a controller 10, a power regulator 20, and a sampler 30.
The controller 10 is configured to set a control signal matched with a preset working voltage according to the preset working voltage of the load, for example, a rated voltage of a corresponding electronic product load, or a corresponding working voltage in a second working state or other working states.
It will be appreciated that the controller 10 may set the control signal to a digital signal with a value of 5 or 3.3 or an analog signal with a corresponding waveform according to a preset operating voltage of the load, for example, when a rated voltage of a corresponding electronic product load is read to be 5V or 3.3V. When the electronic product operates in an abnormal operating state, such as a power saving state or an alarm state, the preset operating voltage may be an operating voltage of another value that is less than or greater than the rated voltage 5V or 3.3V, and accordingly, the controller 10 may also match the control signal with a digital signal or an analog signal corresponding to the waveform that is set to another value.
Wherein, the power regulator 20 is coupled to the controller 10, and the power regulator 20 is configured to receive a control signal sent by the controller 10, so as to convert a voltage signal regulated to a corresponding voltage level when receiving the control signal. It will be appreciated that the power supply regulator 20 incorporates power electronics configured to perform a recognized conversion of an analog control signal or a digital control signal to output a voltage signal of a corresponding waveform.
The sampler 30 is coupled to the controller 10, the power regulator 20, and the load, respectively, and configured to receive a voltage signal sent by the power regulator 20, and send a feedback signal obtained by sampling the voltage signal output by the power regulator 20 to the controller 10, so that the controller 10 can adjust a preset control signal according to the feedback signal to adjust the voltage signal output by the power regulator 20, and send the voltage signal to the load when it is detected that the received voltage signal output by the power regulator 20 is consistent with a preset operating voltage of the load.

In an alternative embodiment, the controller 10 integrates a function list, and when the controller 10 receives the feedback signal sent back by the sampler 30, the function list can be used to calculate the difference between the voltage signal output by the power regulator 20 to the sampler 30 and the preset operating voltage of the load according to the received feedback signal, so as to correspondingly adjust the control signal sent to the power regulator 20 according to the corresponding function mapping relationship, and thus the power regulator 20 can output a voltage signal closer to the preset operating voltage again.
