Ultra-small 5W power solution reduces power loss by 50 percent, enabling faster, more efficient charging
Barcelona (Feb. 25, 2014) – Improving the mobile charging experience, Texas Instruments (TI) introduced the industry’s smallest, most efficient wireless power receiver to support both the Wireless Power Consortium (WPC) 1.1 Qi 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.
Features and benefits of bq51221:
- Dual-mode, 5-watt receiver: Compliant with WPC 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 WPC 1.1-compliant receiver with an integrated 7-V regulated supply and foreign object detection. The single-chip receiver achieves 93 percent power efficiency and ensures the lowest possible power dissipation when charging a Qi-compliant smartphone.
