Abstract
A digital controller for controlling an average-current-mode voltage regulator with an output connected to a load. The controller comprises a digital voltage-sampling window Analog-to-Digital Converter (ADC), based on Delay-Lines (DLs) and configured to obtain a sample of a voltage error signal being the difference between the reference voltage and the output voltage, and to convert the voltage error signal from analog to digital representation; a digital current-sampling window ADC, based on DLs and configured to obtain a sample of the output current and to convert the current output from analog to digital representation; a digital compensator for voltage regulation, receiving as input the digital voltage error signal, configured to generate a current reference signal based thereupon; a digital compensator for current regulation, receiving as input the current error signal and the current reference signal, configured to generate a duty-ratio command signal based thereupon; and a digital hybrid High Resolution (HR) Digital Pulse Width Modulator (HR-DPWM) receiving as input the duty-ratio command signal and generating a pulse-width-modulated signal that is fed to the gates of the converter's transistors, to thereby control the current and voltage supplied to the load.
