Single-Wire Interface PWM Control System

Figure 10. Data Flow for the Single-Wire Interface This topology shows the flow of data for a single-wire interface, pulse width modulation (PWM)-based control system.

The single-wire interface control system uses the PWM of a single signal. An analog process translates that signal into a current that is added to the voltage feedback node of the power supply module. Voltage sense lines and an accurate voltage reference provide the analog-to-digital converter on the FPGA with the resulting voltage level.
