An error amplifier and an amplifying method thereof are provided to minimize the influence of parasitic capacitors of switches connected to a maximum value and a minimum value when outputting an error voltage. An error amplifier(200) includes a differential amplifying unit(210), a control signal generating unit(220), and an output unit(230). The differential amplifying unit amplifies and outputs a difference voltage(Ve) between an input voltage(Vin) and a reference voltage(Vref). The control signal generating unit outputs a control signal by comparing the difference voltage with a maximum voltage(Vmax) or a minimum voltage(Vmin). The output unit outputs any one among an error voltage, the maximum voltage, or the minimum voltage by performing switching based on the control signal. |
