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.

Companies are harnessing data in ways we once associated with science fiction. Analysts have access to a plethora of visualization and reporting tools, but considering the vast amount of data businesses collect and limitations of CPUs, end users are forced to design their structures and systems with limitations. Until now. As the cloud toolkit to analyze data has evolved, GPUs have stepped in to massively parallel SQL, visualization and machine learning.
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?

For example, using spot instances ...
The session is centered around the tracing of systems on cloud using technologies like ebpf. The goal is to talk about what this technology is all about and what purpose it serves. In his session at 21st Cloud Expo, Shashank Jain, Development Architect at SAP, will touch upon concepts of observability in the cloud and also some of the challenges we have. Generally most cloud-based monitoring tools capture details at a very granular level. To troubleshoot problems this might not be good enough.
DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...
