Claim 0:
1. 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 inject an offset voltage to the second voltage signal for dynamically adjusting the second voltage signal during a period in which a target regulated voltage level of the output voltage is a constant;, wherein the voltage adjustment circuit is arranged to detect occurrence of an event to generate a detection result, and refer to the detection result to inject the offset voltage to the second voltage signal; and the second voltage signal has a first constant voltage during a period in which the event does not occur, and the voltage adjustment circuit is arranged to set the offset voltage by a time varying voltage and inject the offset voltage to the second voltage signal during a period in which the event occurs.
