Circuit board and power source management system of circuit board

A circuit board, comprising:

• a power source management system that includes:
• a processor that includes:
• a voltage offset circuit having a first offset voltage output terminal and a second offset voltage output terminal,
• a core voltage input terminal coupled to the first offset voltage output terminal, and
• a core voltage feedback terminal coupled to the second offset voltage output terminal;
• and
• a voltage regulating means that is separate from the processor and includes:
• a controller,
• a setting terminal connected to the controller with a fixed reference voltage provided thereto,
• a detecting terminal connected to the controller and coupled to the core voltage feedback terminal to detect a feedback core voltage from the core voltage feedback terminal, and
• a core voltage output terminal coupled to the core voltage input terminal to provide a core voltage thereto, wherein the core voltage output terminal and the core voltage input terminal are separate terminals,
• wherein the core voltage is regulated by the voltage regulating means based on the feedback core voltage, such that the feedback core voltage is equal to the fixed reference voltage,
• wherein an offset voltage equal to a difference between a desired core voltage of the processor and the fixed reference voltage is provided between the core voltage input terminal and the core voltage feedback terminal by the processor.
