标准范围

IEC 62680-1-2:20 19定义了涵盖USB系统所有元件的电力输送系统，包括:主机、设备、集线器、充电器和电缆组件。本规范描述了管理高达100W的USB供电所需的架构、协议、电源行为、连接器和布线。本规范旨在完全兼容并扩展现有的USB基础设施。本规范旨在为系统原始设备制造商、电源和外围设备开发商提供足够的灵活性，以实现产品多功能性和市场差异化，而不会失去向后兼容性。本第四版取消并取代了2018年出版的第三版，构成技术修订。它也被标识为USB电源传输规范，修订版3。0，版本1.2USB PD规范的此更新版本包含了USB PD 3.0 v1.1中的所有ECN。这使得所有ECN都包含在硬拷贝规范中，从而完成了完整的印刷规范。

IEC 62680-1-2:2019 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.
This fourth edition cancels and replaces the third edition published in 2018 and constitutes a technical revision.
It is also identified as USB Power Delivery Specification, Revision 3.0, Version 1.2
This updated release of the USB PD specification was made to incorporate all the ECNs that were made to USB PD 3.0, V1.1. This makes a full completed printed specifications with all ECNs incorporated into a hard copy specification.
