Assignee: REALTEK SEMICONDUCTOR CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. The power supply method of claim 6, further comprising:
controlling a control transistor of a feedback voltage generation circuit to have a control current when being conducted;
respectively electrically coupling two input terminals of a comparator of the feedback voltage generation circuit to a drain of the switch transistor and a drain of the control transistor, and electrically coupling an output terminal of the comparator to the drain of the control transistor, such that the control current and the operation current have a fixed ratio therebetween; and
respectively electrically coupling a first current output terminal and a second current output terminal of a current mirror of the feedback voltage generation circuit to the drain of the control transistor and an output resistor, so as to mirror the control current to the output resistor and generate the feedback voltage at the second current output terminal.
