Abstract:
The switching regulator has a first switching regulator circuit for outputting a variable power according to a pulse width modulation pulse to be supplied; a second switching regulator circuit for outputting or stopping a constant power according to a control signal to be supplied; and a control circuit for controlling the first switching regulator circuit and the second switching regulator circuits. The control circuit increases the variable power of the first switching regulator circuit by an amount greater than a regular amount if a detected voltage changes from a status higher than the target voltage to a status lower than the target voltage, and decreases the variable power of the first switching regulator circuit by an amount greater than the regular amount if the detected voltage changes from a status lower than the target voltage to a status higher than the target voltage.
