Claim 13:
14. An apparatus, comprising:
a plurality of circuit blocks coupled to a power supply line; and
a power management unit that includes a power converter circuit including a plurality of phase circuits, wherein the power converter circuit is configured to:
generate a regulated power supply signal on the power supply line;
generate a plurality of data bits based on the regulated power supply signal;
perform a comparison of the regulated power supply signal 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 a plurality of control signals; and
wherein the plurality of phase circuits are configured to source respective supply currents to the power supply lines based on corresponding ones of the plurality of control signals.
