Abstract
In an embodiment, an apparatus includes: an amplifier to compare a reference voltage to a feedback voltage and to output a comparison signal based on the comparison; a first loop circuit coupled to the amplifier to receive the comparison signal and output a first feedback voltage for the amplifier to use as the feedback voltage in a first mode of operation; and a second loop circuit coupled to the amplifier. The second loop circuit may be configured to receive the comparison signal and output a second feedback voltage for the amplifier to use as the feedback voltage in a second mode of operation. The second feedback voltage may be greater than the first feedback voltage, and the second loop circuit may output a regulated voltage based on the comparison signal.
