A DC-DC controller and an operation method thereof are provided. The DC-DC controller is configured to connect an output stage. The DC-DC controller includes a pulse width modulation (PWM) calculation circuit, a load transient detection circuit, and an override time calculation circuit. The PWM calculation circuit provides a PWM signal to the output stage. The load transient detection circuit receives an input signal related to an output voltage of the output stage. The load transient detection circuit provides a control signal according to the input signal and a predetermined input signal. The override time calculation circuit provides an override control signal with a predetermined time to the PWM calculation circuit according to the control signal. The PWM calculation circuit adjusts a duty cycle of the PWM signal according to the override control signal.
