VARIABLE-FREQUENCY AND MULTI-PHASE VOLTAGE REGULATOR MODULE AND CONTROL METHOD OF THE SAME |
摘要 |
A control method of a variable-frequency and multi-phase voltage regulator module is provided. The variable-frequency and multi-phase voltage regulator module is connected to a central processing unit and embedded on a motherboard for providing a central-processing-unit current. The control method includes steps of: detecting an intensity of a central-processing-unit current of the central processing unit; providing a power to the central processing unit via M number of phases based on a first switching frequency if the intensity of the central-processing-unit current is greater than a reference-current value; and providing a power to the central processing unit via N number of phases based on a second switching frequency if the intensity of the central-processing-unit current is less than the reference-current value.
