Abstract

The present disclosure relates to average current mode control of digital voltage sources. A digital control signal is generated to control the voltage source. The digital control signal is based on output current of a voltage source and upper and lower signals. The upper and lower signals are based on respective positive and negative offsets and a difference between a reference signal and a feedback signal related to the output voltage.
