DIGITAL PWM CONTROLLER

摘要

A control circuit for a multi-phase converter (30) including an analog front-end circuit (32) for receiving and processing an output voltage and current of the converter circuits and an average output current, a digital circuit (34) for producing an output voltage reference for setting a desired output voltage of the converter, and an error circuit (38) for comparing the output voltage reference and a parameter related to said output voltage and current for generating control signals for controlling the converter circuits, said error circui (38) including an Analog to Digital Converter circuit (26), further comprising a digital PWM generation circuit (18) controlled by said Analog to Digital converter circuit (26) for generating digital control signals for controlling the converter circuits.
