Problems solved by technology
However, each switch chip actually has a different core voltage when it leaves the factory. If the core voltage is set to a fixed value, the fixed value must be higher than the actual value of the switch chip. The current is a fixed value, which invisibly increases the overall power consumption of the switch system
[0003] At the same time, the increase in the overall power consumption of the switch system also leads to an increase in the loss of fans and radiators in the switch system, which increases the noise of the equipment and affects the operating environment of the equipment.

The invention discloses a switch chip voltage regulation method and system, and the method comprises the steps that a controller reads an effective SVB value of a switch chip, converts the SVB value into an I2C code stream, and stores the I2C code stream into a voltage regulation I2C register; the controller outputs the regulation voltage I2C register value to an output voltage register for controlling the output voltage value in the power supply chip, and the power supply chip regulates the output voltage output to the switching chip by the power supply chip according to the output voltage register value; the controller reads back an output voltage register value of the power supply chip and compares the output voltage register value with an adjusting voltage I2C register value; and if the comparison result indicates that the two values are consistent, the controller de-resets the switch chip. The system comprises a controller, an exchange chip and a power supply chip. The overall power consumption of the switch system can be reduced, the loss of the fan and the radiator is reduced, the reliability of dynamic voltage regulation of the switch chip can be verified, and the service life of the switch system is prolonged.
Description
technical field [0001] The invention relates to the field of switch design, in particular to a method and system for regulating the voltage of a switch chip. Background technique [0002] When designing a switch system, for design convenience, the core power supply voltage value of the switch chip is generally set to a fixed value. However, each switch chip actually has a different core voltage when it leaves the factory. If the core voltage is set to a fixed value, the fixed value must be higher than the actual value of the switch chip. The current is a fixed value, which virtually increases the overall power consumption of the switch system. [0003] At the same time, the increase in the overall power consumption of the switch system also leads to an increase in the loss of fans and heat sinks in the switch system, which increases the noise of the equipment and affects the operating environment of the equipment. Contents of the invention [0004] In order to solve the ...
