Toshiba Toshiba has introduced a wireless charging transmitter IC that can output up to 15W - "TC7718FTG".
The new IC is connected to a microcontroller to implement a wireless transmitter system that complies with the Qi[1] standard. This standard was developed by the Wireless Charging Alliance (WPC). Toshiba's original cutting-edge CD-0.13 is built for small package and high efficiency, simplifying system integration and reducing the space occupied by the transmitter system. The new IC provides a 15W wireless transmitter for fast device charging with a charging rate equal to or faster than a wired charger. The new IC is suitable for a wide range of applications, including mobile devices such as smartphones and tablets, as well as industrial equipment.
The wireless transmitter using this new IC will be compatible with the receiver system using the Toshiba 5W receiver IC "TC7764WBG" and the receiver system using the Toshiba 10W receiver IC "TC7765WBG10W", both of which are in volume production. Combined with the Qi V1.2 standard 15W wireless receiver control IC "TC7766WBG", it can receive up to 15W of power.
Let me use the numbers to show you:
The normal mobile phone battery capacity is about 3400mAh/3.6V, and the theoretical talk time is 1380 minutes (3G).
Then it has to be fully charged in one hour (3.4 & TImes; 3.6) = 12.2W
It can be obtained that the 15 watt full charge time is (12.2/15) & TImes; 60 = 48 minutes (theory)
In other words, in less than 50 minutes, you can fly out with a fully charged mobile phone.
Let us do another elementary school math problem:
It is known that Toshiba 15W wireless charging fills a board and only takes 48 minutes.
Then 15W charging for 5 minutes accounted for 5/48 of full capacity.
Then the theoretical talk time for the amount of charge for 5 minutes is 1380&TImes; (5/48) = 143 minutes
This is not the legendary charging for 5 minutes, talking for two hours, no, it should be nearly two and a half hours!
After entering the door, the mobile phone can be charged when it is thrown on the table. When the toilet is back, the mobile phone power is enough for me to call the porridge for two hours. Life has never been so simple.
In addition, Toshiba's "TC7718FTG" is also connected to the microcontroller, in line with the Qi standard; the original cutting-edge CD-0.13 process enables small package and high efficiency; simplifies system integration and takes up less space.
In short, I used this new 15W wireless transmitter IC to charge, at this time wireless wins the cable!
Fast wireless charging is already on the road, are you looking forward to it?

Main specifications
1. Texas Instruments (TI) introduced the industry's first 15W wireless power transmitter bq501210 that complies with the Wireless Charging Alliance (WPC) v1.2 standard and is certified by Qi. The transmitter achieves 84% ​​system efficiency. Compared to traditional wireless power devices, their heat dissipation is significantly reduced. In addition, the transmitter supports multiple fast charging protocols and has a range of flexible, customizable features such as personal electronics, medical and space-constrained industrial applications.
2. Toshiba's storage and electronic components solutions company also announced that the wireless charging transmitter system using Toshiba's "TC7718FTG" 15W wireless charging transmitter IC is certified to meet the Qi V1.2 EPP developed by the Wireless Charging Alliance (WPC). Extended power distribution) standard. The system uses the MP-A2 (a wireless charging transmitter system using a 12V single coil defined by the Wireless Charging Alliance) that supports a simple system configuration. It is the industry's first Qi-certified MP-A2 transmitter system.
