IEC 62680-1-2:2026 pdf download,Universal Serial Bus interfaces for data and power – Part 1-2: Common components – USB Power Delivery specification.
IEC 62680-1-2:2026, known as the USB Power Delivery specification, describes a power delivery system that includes all elements of the USB ecosystem, such as USB hosts, devices, hubs, chargers, and cable assemblies. This standard outlines the required architecture, protocols, power supply operations, connectors, and cabling necessary for effective power delivery via USB at rates of up to 100W in SPR Mode and 240W in EPR Mode. Created to ensure full compatibility with and enhancement of the existing USB infrastructure, this specification offers system OEMs, power supply manufacturers, and peripheral developers the flexibility needed for product versatility and market differentiation, while also ensuring backward compatibility.
IEC 62680-1-2:2026 replaces the seventh edition published in 2024 and includes a technical revision. The document also introduces the Extended Power Range (EPR) capability, which features Adjustable Voltage Supply (AVS). This specification is officially recognized as the USB-IF publication Universal Serial Bus Power Delivery Specification Revision 3.2, Version 1.1.
