[0067] The CPU voltage feedback port VDD_CPU_B_FB is used to output the voltage feedback signal of the large core cluster so that the power management module 500 can adjust the voltage output to the CPU power supply port. The function of the GPU voltage feedback port VDD_GPU_FB is similar to that of the CPU voltage feedback port VDD_CPU_B_FB, and this embodiment of the present disclosure does not limit it.

[0068] In this embodiment, the first voltage regulator 510 and the second voltage regulator 520 can both be SYR837PKC, and this embodiment is not limited to them.
