  • System and method for regulating a load by utilizing pulse width modulation
    Publication number: 20060127066
    Abstract: The invention is directed to a system and method for regulating a load (such as a CPU). A pulse-width-modulation (PWM) regulator calculates the duty cycle of the control pulse from a PWM controller, and then compares the duty cycle to a predetermined threshold. Thereafter, the PWM regulator regulates working conditions, such as clock frequency, supplied voltage, or fan spin speed, based on the above comparison.
