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.

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 Universal Serial Bus Power Delivery Specification Revision
3.0, Version 1.2.
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.
