Abstract
A digital controller for controlling the operation of a DC-DC switching converter is disclosed. A digital feedback control system is provided for receiving an analog input voltage representing the output of the switching converter and digitally processing the analog input voltage by comparing it to a reference voltage and then determining analog drive signals to control the operation of the switching converter to provide a regulated output. The digital feedback control system operates in accordance with predetermined operating parametrics. The digital feedback control system also has monitoring inputs and control inputs. A microcontroller monitors the operation of the digital feedback control system and is able to change the operating parametrics under certain predetermined conditions.
