Claim 7:
8. An output voltage protection controller comprising:
a comparator circuit, arranged to compare 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; and
a voltage adjustment circuit, arranged to receive a sensing signal of an inductor current of the voltage regulator, set an offset voltage according to at least the sensing signal, and inject the offset voltage to the second voltage signal, wherein the voltage adjustment circuit injects the offset voltage to the second voltage signal during a first period, and does not inject the offset voltage 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.
