Abstract
A DC-DC converter includes: an error amplifier for outputting an error between an output voltage and a predetermined voltage; a phase compensation impedance element for accumulating the error across one end to generate an error phase; a determination unit for determining whether the voltage output by the error amplifier is higher, or lower than a reference voltage that is consonant with the predetermined voltage, and outputting a determination signal indicating determination results; and a voltage setting unit for setting a voltage for one end of the phase compensation impedance element higher than a lower output voltage limit for the error amplifier when the determination signal indicates that the voltage output by the error amplifier is lower than the reference voltage, or for canceling setting of the voltage when the determination signal indicates that the voltage output by the error amplifier is higher than the reference voltage.
