Claim 16:
17. An output voltage protection control method comprising:
comparing a first voltage signal with a second voltage signal to generate a control signal that controls output voltage protection of a voltage regulator, wherein one of the first voltage signal and the second voltage signal is a feedback voltage derived from an output voltage of the voltage regulator, and another of the first voltage signal and the second voltage signal is a voltage detection threshold;
receiving a sensing signal of an inductor current of the voltage regulator;
setting an offset voltage according to at least the sensing signal; and
injecting the offset voltage to the second voltage signal, wherein the offset voltage is injected to the second voltage signal during a first period, and is not injected to the second voltage signal during a second period, where one of the first period and the second period is followed by another of the first period and the second period.
