Abstract

The present invention proposes a system for regulating the voltage of a power supply, which includes a module to be adjusted, a power node connected to the module to be adjusted, a voltage regulating switch channel, and a voltage regulating module; the voltage regulating module receives the voltage regulating signal sent by the module to be The voltage module adjusts the charge and discharge to control the opening or closing of the voltage regulation switch channel, and then adjusts the voltage change of the module to be adjusted; the power node provides power for the voltage regulation module and the module to be adjusted; the input terminal of the voltage regulation module is connected to the power node; The output terminal of the module is connected with the module to be adjusted through the channel of the voltage regulating switch. The system also includes a voltage feedback module; the voltage feedback module is used to feed back the adjusted output voltage in real time; the input end of the voltage feedback module is connected to the module to be adjusted, and the output end is connected to the voltage regulation module. The invention can effectively solve the voltage regulation requirement of the high-density board chip due to the power consumption requirement, realize the voltage regulation design of the chip in a smaller space and less power supply chips, and reduce the cost.

Description

technical field [0001] The invention belongs to the technical field of server power supply regulation design, and in particular relates to a system for regulating voltage of a power supply. Background technique [0002] With the development of new Internet technologies such as cloud computing, AI intelligence, and big data, highly integrated chips and high-density boards have emerged as the times require. High-density boards mean tight space for devices, and highly integrated chips bring more powerful functions. , also need more power input and multi-voltage power supply to meet different power demands. When the IC needs to operate at high power, the input voltage will increase accordingly, and at the same current, the power provided by the power supply will be higher; when the IC needs to operate at low power, the input voltage can be reduced accordingly, and the IC While the power consumption itself is reduced, it also reduces the loss on the path and saves power. When a...
