Description

Technical Field

[0001] This application relates to the field of server technology, specifically to a control system for a voltage chip and a server. Background Technology

[0002] Currently, circuit boards in servers are equipped with voltage chips that convert the power supply voltage into the power supply voltage required by the target components, thereby providing power to the target components on the circuit board.

[0003] The existing voltage chip outputs a supply voltage through a fixed voltage divider resistor connected to its feedback pin. This voltage divider resistor is connected to the power supply voltage to form an output voltage regulation bypass. This allows the power supply voltage to pass through the voltage divider resistor and receive a fixed voltage signal at the feedback pin. The voltage chip then converts the power supply voltage into a fixed supply voltage based on this voltage signal.

[0004] Therefore, once the existing voltage chip is soldered onto the circuit board, its output voltage cannot be adjusted. If the output voltage needs to be adjusted, the corresponding voltage divider resistor must be replaced and soldered. Furthermore, as the voltage divider resistor ages, its resistance changes, causing fluctuations in the voltage chip's output voltage. This affects the power supply to the target components and consequently, the normal operation of the server. Summary of the Invention

[0023] It should be noted that in the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural. The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and drawings of this application are used to distinguish similar objects, not to describe a specific order or sequence.

[0024] It should also be noted that the methods disclosed in the embodiments of this application or the methods shown in the flowcharts include one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged, and some steps can also be deleted.

[0025] Currently, circuit boards in servers are equipped with voltage chips that convert the power supply voltage into the power supply voltage required by the target components, thereby providing power to the target components on the circuit board.

[0026] The existing voltage chip outputs a supply voltage through a fixed voltage divider resistor connected to its feedback pin. This voltage divider resistor is connected to the power supply voltage to form an output voltage regulation bypass. This allows the power supply voltage to pass through the voltage divider resistor and receive a fixed voltage signal at the feedback pin. The voltage chip then converts the power supply voltage into a fixed supply voltage based on this voltage signal.

[0027] Therefore, once the existing voltage chip is soldered onto the circuit board, its output voltage cannot be adjusted. If the output voltage needs to be adjusted, the corresponding voltage divider resistor must be replaced and soldered. Furthermore, as the voltage divider resistor ages, its resistance changes, causing fluctuations in the voltage chip's output voltage. This affects the power supply to the target components and consequently, the normal operation of the server.

[0028] This application provides a control system and server for a voltage chip, which can adjust the output voltage of the voltage chip and prevent fluctuations in the output voltage of the voltage chip, so that the server can maintain stable operation.
