Overview
IEC 62680-1-2:2022 is an international standard developed by the International Electrotechnical Commission (IEC), outlining requirements and best practices for Universal Serial Bus (USB) Power Delivery (PD). This sixth edition, based on the USB-IF Universal Serial Bus Power Delivery Specification Revision 3.1, Version 1.1, defines the architecture, protocols, connectors, and power management for delivering up to 100W of power across USB systems. It supports a wide range of USB components, including hosts, devices, hubs, chargers, and cable assemblies.
The specification ensures seamless and safe power negotiation between devices, maintaining full backward compatibility and promoting system versatility. The latest revision introduces features such as the Extended Power Range (EPR) and Adjustable Voltage Supply (AVS), enhancing the scope and efficiency of USB power solutions in modern electronic devices.
