Wireless power sources for recharging mobile devices, including wearable electronics and mobile phones, are becoming increasingly popular because of the convenience of going cordless. But a common concern with early forms of wireless power designs was their relatively low operating efficiency. Low efficiency leads to generation of extra heat – and we know that heat is bad for long-term battery life, especially in the case of the Li-Ion batteries used in most mobile devices. So, we really need to consider ways of minimizing heat generation and wasted power if we want our batteries to have a long service life.
By maximizing efficiency in the wireless power stage – and then combining that with a high-efficiency switch mode charge controller – you can minimize the heat generated in the process of charging your batteries. Check out the following video from TI and Avnet to learn about how wireless power works – and how technology from TI operates with high efficiency when charging your portable device.
Wireless charging before TI was practically useless. Tried several products but they were either too slow or not reliable. Somehow fell that TI also made wireless charging more affordable. bought a charging set from this site. Pretty cool stuff!
Thanks for your comment! Our wireless charging product family continues to grow, and we hope that wireless power will become a reality for many more products in the years ahead. We appreciate your interest and use of our technology!
