Texas Instruments Announces First Qi-Certified 15-W Wireless Power Transmitter
Texas Instruments (TI) introduced the industry’s first Wireless Power Consortium (WPC) v1.2 Qi-certified 15-W wireless power transmitter. The bq501210 enables 84 percent system efficiency with significantly less thermal dissipation than traditional wireless power devices. The transmitter supports multiple fast-charging protocols and offers an array of flexible and customizable features such as personal electronics, medical and space-constrained industrial applications.

The new 15-W transmitter joins TI’s proven portfolio of scalable wireless power solutions, which also includes 2.5-W, 5-W and 10-W products that provide designers with best-in-class thermal ratings and wide input-voltage and output power ranges, along with customizable sizes and power levels to fit a wide variety of wireless power needs. These solutions enable efficient wireless charging capabilities for mobile phones, tablets and other portable electronics, and wireless power charging transmitters ranging from stand-alone charging pads to those embedded in cars and furniture.

This breakthrough in technology enables connectorless models and reduces overall end-application size by helping eliminate the need for bulky wiring. System efficiency at 84 percent: Fixed-frequency operation helps achieve the industry's highest 15-W efficiency as well as reducing electromagnetic interference (EMI). Fast-charge negotiation with mobile devices enables the transfer of up to 10 W to compatible receivers, including existing fast-charging devices on the market.
 

The High-Voltage Dedicated Charging Port (HVDCP) protocol negotiates with capable AC/DC wall adapters to adjust the input voltage. The rail control output provides power to deliver a full 15 W with inputs between 15 V and 19 V, and enables lower power operation, such as 5 W, with inputs as low as 5 V.

To speed time to market and easily evaluate the new device’s features and performance, TI also released the bq501210 evaluation module (EVM), available for US$149. The bq501210 transmitter is shipping in volume production now and comes in a 9-mm-by-9-mm very thin quad flat no-lead (VQFN) package and is priced at US$3.75 in 1,000-unit quantities.
