Display driving chip, voltage regulating method and related equipment

The invention relates to the technical field of chips, in particular to a display driving chip, a voltage regulating method and related equipment, and a DDIC comprises a controller and a voltage stabilizer. The controller is coupled with the first power supply chip, and the voltage stabilizer is coupled with the second power supply chip; wherein the first power supply chip is used for providing a first voltage for the controller; the second power supply chip is used for providing a second voltage for the voltage stabilizer; the voltage stabilizer is used for providing a third voltage for the controller based on the second voltage; the controller is used for controlling the voltage stabilizer to adjust the voltage value of the third voltage through the control signal; when the voltage value of the third voltage is smaller than that of the first voltage, the working current of the controller is provided by the first voltage; when the voltage value of the third voltage is larger than or equal to the voltage valu
