    Wireless Fast-Charge Tech Enables a World of Possibilities

    15-watt Qi extension is ready and waiting for mobile phone users, designers, and service providers.

    Wireless charging has captured the imagination of mobile phone users, designers, and service providers. Now, with the introduction of the 15-watt extension to the Qi specification, a new world of products and capabilities has opened up.

    While previously the benefits of wireless charging had been limited to charging mobile phones at five watts (on par with typical wired charging), the convenience and reliability of wireless charging has made it a “must-have” in many smartphone feature check-lists. Recent announcements from IKEA and Samsung have hastened the adoption of this convenient charging technology.

    The first new benefit of the increased power is the ability of mobile phone manufacturers and after-market accessory makers to offer wireless fast-charge capability.

    Wireless Fast-Charge Tech Enables a World of Possibilities

    The first new benefit of the increased power is the ability of mobile phone manufacturers and after-market accessory makers to offer wireless fast-charge capability. This new technology goes by various names: Quick Charge 2 from Qualcomm, Adaptive Fast Charging, from Samsung, TurboPower from Motorola, and BoostMaster from Asus. What these charging systems all have in common is that they can take advantage of 15W sources like USB-3 (5V/3A) and new 9V/1.67A chargers.

    How fast is this new charging technology? Up to 75% faster than conventional charging. Qualcomm conducted a test that compared three charging approaches. The phones all used a 3300mAh battery and charged for 30 minutes. Following are the results:

    from 0% to 60% with Quick Charge 2.0 (9 volt/1.67 amp, 15W)
    from 0 to 30% with Quick Charge 1.0 (5 volt/2 amp, 10W)
    from 0% to 12% with a conventional charger (5 volt/1 amp 5W)

    The latest Qi specification enables device manufacturers to extend this speed to wireless charging. In addition, the 15W extension supports the ability to wirelessly charge tablet computers at rates similar to wired charging. Asus tablets come with 10-watt chargers and Apple iPads come with 12W chargers. That means that these digital marvels can also take advantage of wireless charging without any charging speed tradeoffs.

    Mobile Qi download speeds up significantly

    With medium power definitions charging efficiency rises to 15 watts. At the same time determinations were added to better function for detecting foreign objects, allowing, for example, the charging platform Guests metal objects are identified before the start of the charging process. Such an object could cause overheating

    ROHM says the launch of certified during the BD57015GWL transmitter circuit production in December.

    Research IHS According to the current year will be wireless charging breakthrough year. Wireless Number of exploiting downloading applications has increased dramatically. Last year, the wireless charging transmitter circuits sold 55 million copies. In 2018, the number will grow to nearly 1.1 billion and in 2024 up to 2.3 billion, IHS predicts.

    Wireless Charging begins to be more expensive smartphones as a standard feature, but the development of technology will take it as soon on the tablets.

    Toshiba Electronics praises to introduce its first 15-watt power charging circuit that is compatible with the WPC-organization, ie, the Wireless Power Consortium Qi technology with the 1.2 version.

    TC7766WBG-circuit is Toshiba’s new circuit is packaged in 2.4 x 3.67mm WCSP-housing.
    The output voltage is adjustable 5-14 volts.
