FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities,
IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature
whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of,
or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62680-1-2 has been prepared by technical area 14: Interfaces and methods
of measurement for personal computing equipment, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.
This third edition cancels and replaces the second edition published in 2017 and constitutes a technical
revision.
The text of this standard was prepared by the USB Implementers Forum (USB-IF). The structure and
editorial rules used in this publication reflect the practice of the organization which submitted it.

Full information on the voting for the approval of this International Standard can be found in the report
on voting indicated in the above table.
The committee has decided that the contents of this document will remain unchanged until the stability
date indicated on the IEC website under "http://webstore.iec.ch" in the data related to the specific
document. At this date, the document will be
• reconfirmed,
• withdrawn,

INTRODUCTION
The IEC 62680 series is based on a series of specifications that were originally developed by the USB
Implementers Forum (USB-IF). These specifications were submitted to the IEC under the auspices of a
special agreement between the IEC and the USB-IF.
This standard is the USB-IF publication USB Power Delivery Specification Revision 3.0 V.1.1 and ECNs
through 12 June 2017.
The USB Implementers Forum, Inc.(USB-IF) is a non-profit corporation founded by the group of
companies that developed the Universal Serial Bus specification. The USB-IF was formed to provide a
support organization and forum for the advancement and adoption of Universal Serial Bus technology.
The Forum facilitates the development of high-quality compatible USB peripherals (devices), and
promotes the benefits of USB and the quality of products that have passed compliance testing.
ANY USB SPECIFICATIONS ARE PROVIDED TO YOU "AS IS, "WITH NO WARRANTIES
WHATSOEVER, INCLUDING ANY WARRANTY OF MERCHANTABILITY, NON-INFRINGEMENT, OR
FITNESS FOR ANY PARTICULAR PURPOSE. THE USB IMPLEMENTERS FORUM AND THE
AUTHORS OF ANY USB SPECIFICATIONS DISCLAIM ALL LIABILITY, INCLUDING LIABILITY FOR
INFRINGEMENT OF ANY PROPRIETARY RIGHTS, RELATING TO USE OR IMPLEMENTATION OR
INFORMATION IN THIS SPECIFICAITON.
THE PROVISION OF ANY USB SPECIFICATIONS TO YOU DOES NOT PROVIDE YOU WITH ANY
LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE, TO ANY INTELLECTUAL
PROPERTY RIGHTS.
Entering into USB Adopters Agreements may, however, allow a signing company to participate in a
reciprocal, RAND-Z licensing arrangement for compliant products. For more information, please see:
http://www.usb.org/developers/docs/

IEC DOES NOT TAKE ANY POSITION AS TO WHETHER IT IS ADVISABLE FOR YOU TO ENTER INTO
ANY USB ADOPTERS AGREEMENTS OR TO PARTICIPATE IN THE USB IMPLEMENTERS FORUM.”
