1. An apparatus, comprising:
a plurality of phase circuits coupled to a regulated power supply line via a corresponding plurality of inductors and configured to modify a voltage level of the regulated power supply line using respective ones of a plurality of control signals;
an analog-to-digital converter circuit configured to generate a plurality of data bits based on a voltage level of the regulated power supply line; and
a control circuit configured to:
perform a comparison of the voltage level of the regulated power supply line to a threshold value;
generate a plurality of digital control words using a result of the comparison and the plurality of data bits; and
convert the plurality of digital control words to respective analog values to generate the plurality of control signals.
