ABSTRACT:
A switching regulator of which efficiency is increased while the switching regulator is operated under low load condition is disclosed. The switching regulator is arranged by: a reference voltage circuit for producing a reference voltage; an error amplifier for entering thereinto the reference voltage and a measuring voltage produced by subdividing an output voltage from the switching regulator and for amplifying a difference voltage between the reference voltage and the measuring voltage; an oscillator circuit for outputting an oscillator signal; a PWM comparator for comparing an output voltage of the error amplifier with an output voltage of the oscillator circuit; load detecting means for detecting an output load current; and efficiency varying means for varying an efficiency of the switching regulator in response to load conditions detected by the load detecting means.
