Abstract
A control device for adjusting the output voltage of a voltage generator, wherein the control device includes a master circuit, a slave circuit, and a power-scaling control circuit, is provided. The master circuit is coupled to a system bus. The slave circuit is coupled to the system bus. The power-scaling control circuit is coupled between the master circuit and the slave circuit. In response to the master circuit sending a voltage-scaling command, the power-scaling control circuit sets a control signal at a suspension level so that the slave circuit sets a specific signal transmitted by the system bus at a wait level. In response to the specific signal being at the wait level, the master circuit stops accessing the first specific device of the slave circuit. In response to the control signal being at the suspension level, the power-scaling control circuit adjusts the output voltage.
