First Claim
1. A control system to control an output regulator, the output regulator to convert an input voltage to a regulated output, the output regulator including a power stage to generate a power output from the input voltage and an output filter to filter the power output to generate the regulated output, the control system comprising:
- a digital controller, responsive to a sense signal corresponding to the regulated output, to generate a drive signal to control the power stage, the digital controller including and selecting between at least three operating modes, a selected one of the operating modes to generate the drive signal, wherein said digital controller switches from each of said at least three operating modes to remaining ones of said at least three operating modes based on said sense signal.
