The invention discloses a digital power source based on PMBus. The digital power source comprises a main circuit power circuit and a digital control management unit. The digital control management unit comprises a PMBus digital controller, an ADC sampling conditioning circuit, a processor and a display terminal. The PMBus digital controller is connected with the main circuit power circuit and used for controlling the output voltage of the main circuit power circuit. The ADC sampling conditioning circuit is used for sampling the input voltage, the input current, the output voltage and the output current of the main circuit power circuit, and the ADC input voltage, the ADC input current, the ADC output voltage and the ADC output current are obtained respectively. The processor is used for transmitting the information of the ADC input voltage, the ADC input current, the ADC output voltage and the ADC output current to the display terminal. The digital power source is accurate in output voltage control, timely in fault signal response and capable of monitoring and controlling the input and output voltage and current, the temperature and the working state.
