Universal serial bus interfaces for data and power - Part 1-2: Common components - USB Power Delivery specification

Scope

IEC 62680-1-2:2024 The USB Power Delivery specification defines a power delivery system covering all elements of a USB system including Hosts, Devices, Hubs, Chargers and cable assemblies. This specification describes the architecture, protocols, power supply behavior, connectors and cabling necessary for managing power delivery over USB at up to 100W. This specification is intended to be fully compatible and extend the existing USB infrastructure. It is intended that this specification will allow system OEMs, power supply and peripheral developers adequate flexibility for product versatility and market differentiation without losing backwards compatibility.

IEC 62680-1-2:2024 cancels and replaces the sixth edition published in 2022 and constitutes a technical revision.

Extended Power Range (EPR) including Adjustable Voltage Supply (AVS) has been added. This document is the USB-IF publication Universal Serial Bus Power Delivery Specification Revision 3.2, Version 1.0.
