1. A switching power converter controller, wherein the switching power converter controller controls a plurality of pulse-width-modulated switching power converters, each switching power converter being controlled to regulate power supplied to its own load, comprising:
- an analog-to-digital converter configured to provide, for each switching power converter, a corresponding digital version of an analog feedback signal; and
a processor configured to control the pulse widths for each switching power converter so as to independently regulate the power supplied from each switching power converter to the switching power converter'"'"'s own load, wherein the pulse widths for the switching power converters are defined with respect to a single period; and
wherein the processor is further configured to control the pulse widths for each switching power converter by processing the corresponding digital version to determine a desired pulse width and commanding the switching power converter to pulse according to the desired pulse width, the controller being configured to operate in a pipelined fashion such that while the analog-to-digital converter is providing the digital version for a given one of the switching power converters, the processor is determining the desired pulse width for a remaining one of the switching power converters.

10. A switching power converter controller, wherein the switching power converter controller controls a plurality of pulse-width-modulated switching power converters, each switching power converter being controlled to regulate power supplied to its own load, comprising:
-
an analog-to-digital converter configured to provide, for each switching power converter, a digital version of a load voltage; and a programmable controller configured to control the pulse widths for each switching power converter so as to independently regulate the power supplied from each switching power converter to the switching power converter'"'"'s own load, wherein the pulse widths for the switching power converters are defined with respect to a single period; and
wherein the programmable controller is further configured to control the pulse widths for each switching power converter by processing the corresponding digital version to determine a desired pulse width and commanding the switching power converter to pulse according to the desired pulse width, the switching power converter controller being configured to operate in a pipelined fashion such that while the analog-to-digital converter is providing the digital version for a given one of the switching power converters, the programmable controller is determining the desired pulse width for a remaining one of the switching power converters. - View Dependent Claims (11, 12, 13)
