NXP Introduces High-Power Wireless Charging Solution for Laptops and 2-In-1 Tablets
NXP Semiconductors announced the first high-power wireless charging solution for notebooks and 2-in-1 tablets, providing up to 100W of power and covering the full power range requirements of the sector. The solution is less than 2mm thick and has a low component count, enabling it to meet the most demanding industrial design requirements. At the same time, it provides up to 94% power transfer efficiency, eliminating heat and cooling concerns and costs. The extended z-axis charging distance allows the charging transmitter to be mounted under a table or other surface, and the large spatial freedom in the x-y plane provides a seamless user experience.
Wireless charging products have been a popular accessory for smartphones and other small portable electronics. However, portable computing devices require far more power than can be provided by a smartphone charger. This latest NXP solution allows consumers to enjoy a true cable-free experience when using laptops and 2-in-1 tablets and even meet higher power consumption requirements. Consumers will benefit from the portability and freedom of wireless charging. For many years, consumers have been able to wirelessly connect mice, keyboards, and headsets, as well as wirelessly connect to the Internet, yet remain inseparable from the power cord. With this solution, portable computing device companies can allow users to get rid of the last cable.
Steve Tateosian, director of solutions marketing at NXP Semiconductors, said: "This technology eliminates the traditional power delivery model that requires power cords and outlets and can easily match the form factor and power range of existing products, minimizing changes to end product design and delivering a substantial value experience for end users. Our focus from the beginning has been on providing a comprehensive and flexible solution that can be quickly adopted by customers in the portable computing space."
The Wireless Charging Consortium (WPC) has dedicated specific working groups to develop efficient and safe wireless charging standards for laptops, 2-in-1 tablets, and other products requiring 30-200W power delivery. As a member of the WPC committee, NXP is committed to fully supporting the wireless charging industry standards developed by this working group.
The mass adoption of wireless charging requires an industry standard supported by a wide range of companies, end-product manufacturers, and component suppliers," said WPC Chairman Menno Treffers. "NXP is one of the key drivers of standardization for 30-200W wireless power delivery, and this announcement demonstrates that we are very close to being able to safely deliver power without the use of connectors and cables to safely and efficiently charge computers."
NXP's high-power wireless charging solution consists of a charging pad, or transmitter, that can be placed on a desktop or mounted under the surface; and a receiver that can be integrated into a laptop or 2-in-1 tablet. The solution is fully tested and documented, and NXP can provide development hardware directly, as well as a complete component list and development software to support rapid time-to-market.
