Abstract
In one 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 loop circuit coupled to the amplifier, where the loop circuit is to receive the comparison signal and provide a regulated voltage to the amplifier as the feedback voltage in a first mode of operation, and in a second mode of operation to provide a predetermined feedback ratio point to the amplifier as the feedback voltage; and an output device coupled to the amplifier. The output device may be configured to receive a supply voltage and the comparison signal and output the regulated voltage at an output node based at least in part on the comparison signal.
