WHAT ARE STANDARDS?

Developed based on guiding principles of openness, balance, consensus, and due process.

Established in order to meet technical, safety, regulatory, societal and market needs.

Catalysts for technological innovation and global market competition.

TODAY’S CHALLENGE

Significant advancement in semiconductor technology and performance metrics have had a tremendous impact on the board level power infrastructure.

The need to have products that are innovative enough to address these metrics while still allowing support of a supply assurance program. In order to achieve this, the power supply is quickly adding a digital dimension to the equation.

WHAT’S HAPPENING IN MOBILE NETWORKS AND DATA CENTERS?

Data center IP traffic up from2.5 Zettabytes p.a. in 2012 to7.7 Zettabytes p.a. in 2017*

Mobile network traffic will grow 10X from 2013 to 2019, reaching 19 Exabytes per month*

Demand for processing power rising, driving continued semiconductor innovation

Power-per-board up from 300 W in the 1980s to 3 kW by the end of 2015, 5 kW by 2020

TECHNOLOGIES ARE PROLIFERATINGOUTSIDE TELECOMMUNICATIONS AND SERVER MARKETS

Greater complexity and management of multi-rail semiconductors, FPGAs, processors, DSPs, etc, - products that are used throughout all market segments, including medical, industrial, consumer, and test & measurement.

Geometry advancement in semiconductors has created a requirement of tighter tolerances and flexible architecture to support dynamic core voltage adjustments.

Increased density of boards in technology products continue to increase, yet board space to implement this incremental growth continues to shrink, requiring greater function and density consolidation.

“The market for digital power solutions is already well-established in the server and telecommunication markets,” said Jonathon Eykyn, power supply and storage component analyst for IHS. “However, IHS is now starting to see growing adoption across a much broader range of products and applications, which is driving rapid growth.”

POWERING TOMORROW’S SYSTEMS THE CHALLENGES

How to drive up efficiency, reduce emissions and cut costs

How to monitor and control increasingly complex systems

How to create secure component supply chains for mission critical applications

POL current requirements – already at100 A and may rise to over 400 A in data centers and IP networks

Digital power is particularly effective for improvingefficiency under low-load conditions

POWER SUPPLIER DRIVERS

The drive to perfect power—always

Integrator of technologies, how do they differentiate?

When to lead? When to align?

The industry has changed now that digital is quickly growing—and continues to move faster than it has in the past

Customers still want it all

WHY ARE STANDARDS NEEDED FOR POWER?

Supply chain security

Provides customers with options

Avoid “reinventing the wheel” for each new product

Accelerate innovation

Accelerate efficiency improvements

COMMUNICATION STANDARD

Established standards already exist

SMBus

The physical connection. A long standing protocol used by most organizations already on their board designs.

PMBus

An open power-management protocolwith fully defined commands.

DESIGN WHAT DOES IT DO FOR YOU?

The requirement of intelligent or digital power supplies are quickly proliferating throughout the electronics segment, it is no longer just a datacom/telecom sector requirement.

Digital power supplies are inherently more complicated, this is a burden on suppliers and customers.

Standards supporting members provide a variety of products that cover a wide range of densities, footprints, and features in order to allow the design engineer the best options to meet their requirements.

SUPPLY WHAT ARE THE LIMITATIONS

Supply assurance programs are a requirement by many customers and the advent of digital power complicates this requirement.

Many considerations need to be taken into account because mechanical specifications alone will not allow for a digitally controlled power supply to be multi-sourced by another vendor.

Each group defines compatibility differently.

All standards groups have a minimum number of suppliers that need to provide a product prior to promoting it as an approved product.

13

STANDARDS MUST BE PROACTIVE

Standards groups must be proactive intheir engagements and have a visionary roadmap.

The industry cannot move faster than the standard groups or other groups will step in to fill the gap left.

CONCLUSION

Standards are essential to the continued growth of future technologies

One standard/consortium does not fit all

Interoperability between standards will be limited due to the nature of proprietary digital development

Standards must continue to adapt and develop faster than the adoption
