Power in Consumer Electronics: The New Model

Wednesday, Nov 4, 2015 - 7:00 pm to 9:00 pm          


Since every microwatt counts in mobile consumer electronics, what does it take to create truly power-efficient devices?  What improvements have we seen in efficiency standards, light‐loading optimization techniques and standby modes?

Power delivery of up to 100W is now possible alongside high-speed data lines using Power over Ethernet (PoE), USB Power Delivery and Thunderbolt.  While the extra power is great, it brings a host of challenges for power integrity, signal integrity, intelligent power management, global system efficiency, and potential design overprovisioning.

This talk will explore these issues, and the key aspects of how power is consumed in today’s electronics devices, in a discussion of the “power landscape.”  It was also explore recent trends in the quest for high efficiency and lower power, including how those unsightly “wall wort” A/C power adapters are being miniaturized and often eliminated.
