TI delivers highest efficiency dual-mode Qi, PMA wireless power receiver

First dual-mode 5-W power solution to ship in volume production reduces power loss by 50 percent -- enabling faster, more efficient charging

BARCELONA, Spain, Feb. 27, 2014 /PRNewswire/ -- Improving the mobile charging experience, Texas Instruments (TI) (NASDAQ: TXN) today announced it is shipping in volume production the industry's smallest, most efficient wireless power receiver to support both the Wireless Power Consortium's (WPC) Qi 1.1 and Power Matters Alliance (PMA) specifications. The new bq51221 inductor-less, 5-watt receiver's high efficiency and programmable output reduces power loss by as much as 50 percent compared to existing receiver solutions, allowing consumers to more efficiently and quickly charge their mobile phones, headsets and power banks from a Qi or PMA charging station. To order samples and a development kit, visit: www.ti.com/bq51221-pr

Features and benefits of bq51221:

  • Dual-mode, 5-watt receiver: Compliant with Qi 1.1 and PMA communication and control.
  • High efficiency for fast charge time: Achieves up to 96 percent power efficiency, and the device's adjustable output voltage helps reduce power loss by as much as 50 percent.
  • Industry's smallest, thinnest solution: 3.6-mm by 2.9-mm by 0.5-mm single-chip wireless power receiver achieves a solution size of 75 mm2 without the need for an inductor.

In addition to the dual-mode receiver, TI also introduced its bq51010B next-generation Qi 1.1-compliant receiver with an integrated 7-V regulated supply and foreign object detection. The single-chip receiver, also shipping in volume production, achieves 93 percent power efficiency and ensures the lowest possible power dissipation when charging a Qi-compliant smartphone.

"Storpool does only block-level storage so we do one thing extremely well. The growth in data is what drives the move to software-defined technologies in general and software-defined storage," explained Boyan Ivanov, CEO and co-founder at StorPool, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javits Center in New York City.
You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
Is advanced scheduling in Kubernetes achievable?Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations?

A strange thing is happening along the way to the Internet of Things, namely far too many devices to work with and manage.

Enter the conversational interface revolution, combining bots we can literally talk with, gesture to, and even direct with our thoughts, with embedded artificial intelligence, whic...
The cloud era has reached the stage where it is no longer a question of whether a company should migrate, but when. Enterprises have embraced the outsourcing of where their various applications are stored and who manages them, saving significant investment along the way. Plus, the cloud has become a defining competitive edge. Companies that fail to successfully adapt risk failure. The media, of course, continues to extol the virtues of the cloud, including how easy it is to get there. Migrating...
The use of containers by developers -- and now increasingly IT operators -- has grown from infatuation to deep and abiding love.
