A transient boost controller for controlling a transient boost circuit of a voltage regulator includes a feedback circuit and a processing circuit. The feedback circuit obtains a first feedback signal and a second feedback signal sensed from an output capacitor of the voltage regulator, wherein the first feedback signal is derived from a voltage signal at a first plate of the output capacitor, and the second feedback signal is derived from a voltage signal at a second plate of the output capacitor. The processing circuit generates a detection result according to the first feedback signal and the second feedback signal, and outputs the detection result for controlling the transient boost circuit of the voltage regulator.
