摘要
An error amplification circuit includes an integrated circuit and a phase compensation capacitor. The integrated circuit includes an error amplifier to amplify a difference between a predetermined reference voltage and an input feedback voltage for output; a current generator circuit to generate a bias current for supply to the error amplifier; a phase compensation resistor; a bias-current control terminal; and a phase compensation terminal connected to an output terminal of the error amplifier via the phase compensation resistor. The phase compensation capacitor is connected to the phase compensation terminal, the phase compensation capacitor being provided outside the integrated circuit.
