Abstract
A control device is used to adjust an output voltage of a voltage generator, and includes a master circuit, a slave circuit, and a power-scaling control circuit. The master circuit is coupled to a first bus. The slave circuit is coupled to a second bus. In a normal mode, the first and second buses are connected to each other via the power-scaling control circuit, the master circuit accesses the slave circuit via the first and second buses. In an adjustment mode, the power-scaling control circuit controls the master circuit to stop accessing the slave circuit, and the power-scaling control circuit adjusts the output voltage. When the master circuit sends a trigger signal, the power-scaling control circuit enters the adjustment mode. When the master circuit does not send the trigger signal, the power-scaling control circuit enters the normal mode.
