1. A multi-port charger, comprising:
an AC-to-DC power converter that receives an AC input voltage and generates a DC output voltage therefrom; and
a plurality of integrated power delivery modules electrically coupled to the AC-to-DC power converter and in signal communication with a digital communication bus;
wherein each of the integrated power delivery modules comprises:
a module controller in signal communication with the digital communication bus;
a USB Power Delivery controller (“PD controller”) in signal communication with the module controller and which is configured to be connected to a sink device adhering to a USB standard;
a switch-mode DC-to-DC power converter in signal communication with the module controller and the PD controller and which is configured to provide an adjustable output voltage to the sink device via a USB voltage bus;
a first analog-to-digital converter (ADC) circuit in signal communication with the PD controller and the USB voltage bus to generate a digital representation of the output voltage provided by the switch-mode DC-to-DC power converter to the sink device; and
a second ADC circuit in signal communication with the PD controller and the USB voltage bus to provide a digital representation of an output current provided by the switch-mode DC-to-DC power converter to the sink device.
