    摘要: A method and an apparatus to regulate voltage supply have been disclosed. In one embodiment, the apparatus includes a power converter block to generate an output voltage from an input voltage and a voltage regulator controller coupled to the power converter block to input at least one time-modulated signal to the power converter block, the at least one time-modulated signal having a duty cycle, the voltage regulator controller including a counter having an increment value substantially proportional to the input voltage, wherein the counter is used to adjust the duty cycle of the at least one time-modulated signal. Other embodiments have been claimed and described.
