Configurable integrated power delivery module with adaptive power sharing

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.
