Abstract
An output detection feedback section () for controlling the power supply output voltage of a converter unit () in response to an error signal Ve has an error amplifier () for outputting the error signal Ve, a phase compensation circuit (), a state detection circuit (), and a response compensation circuit () for setting the voltage of a capacitor () of the phase compensation circuit () to a predetermined value. When output voltage is switched, the output voltage is fixed at the predetermined value in a DC manner while a transitional response of the error signal (Ve) is accelerated, so that the output voltage is changed at a high speed to a desired value and the overshoot and undershoot are suppressed around the desired value.
