Claim:
1. A digital error feedback system comprising: a power supply for supplying an input power; a power converter coupled with the power supply, wherein the power converter produces an output voltage on a load using the input power; a digital-to-analog converter (DAC) coupled to the power converter; a first digital signal generator that generates a digital reference signal; and a digital comparator coupled with the first digital signal generator and the DAC, wherein, based on the digital reference signal and a frequency of a digital feedback signal representing the output voltage, the digital comparator produces a digitally compared control signal that is received by the DAC and converted to an analog signal, and further wherein the DAC transmits the analog signal to the power converter such that the digitally compared control signal, as converted to the analog signal, causes the power converter to adjust the output voltage.
