Abstract
A digital power supply system including a microcontroller, a driver, a step down circuit, and a buck and boost circuit is disclosed. The microcontroller circuit provides a first and second plurality of pulse width modulated signals and receives signals indicative of an input current, input voltage, output current, output voltage, and a 3.3 volt supply. The driver receives the first plurality of pulse width modulated signals and a 12 volt supply and provides a DC power signal and the signal indicative of the output current. The step down circuit receives a positive input voltage and provides the 3.3 volt supply. The boost circuit receives the 3.3 volt supply and provides the 12 volt supply. The buck and boost circuit receives the second plurality of pulse width modulated signals and provide the signals indicative of the output voltage, the input current, the input voltage, and the positive input voltage.
