An accelerated output stabilizer and a DC-DC converter for fast load regulation using the same are provided to increase response speed of the output stabilizer by additionally supplying integration acceleration current to an integrator when an output feedback voltage is different from a reference voltage. A proportional amplifier(330) performs a proportional amplification process on output feedback voltage. An integrator(310) integrates input voltage. A voltage buffer(320) has high input impedance and low output impedance, buffers the output feedback voltage and supplies to the integrator. An integration acceleration current generator(370) compares the output feedback voltage with a reference voltage and generates positive integration acceleration current when the output feedback voltage is higher than the reference voltage. When the output feedback voltage is lower than the reference voltage, the integration acceleration current generator generates negative integration acceleration current and supplies to the integrator. |
