Classification: CPC G  H | IPC G  H

Claim 0:
1. An apparatus, comprising:
a first plurality of power drivers and a second plurality of power drivers coupled to a load to supply an output voltage to the load; and
a controller coupled to the first and second pluralities of power drivers, wherein the controller is to implement a first loop to provide fine control bits to the first plurality of power drivers according to a difference between a first reference voltage and the output voltage, and to implement a second loop to provide coarse control bits to the second plurality of power drivers according to a difference between a second reference voltage and the output voltage, wherein the fine control bits indicate a number of power drivers to turn on among the first plurality of power drivers, the coarse control bits indicate a number of power drivers to turn on among the second plurality of power drivers, and a current step size of the coarse control bits is greater than a current step size of the fine control bits.
