What is the difference between the GaN charger and other chargers?
More and more people who care about the mobile phone industry have noticed "GaN", a term that has appeared more frequently recently. The term "gallium nitride" began to appear widely in the public's field of vision with "Xiaomi 65W GaN charger" launching. But, what is the difference between the GaN charger and other chargers? Please refer to the opionions as following:
Different materials are the root of all the different.
The basic material of traditional normal chargers is silicon, which is also a very important material in the electronics industry. But as the limits of silicon gradually approached, the development of silicon also reached a certain bottleneck, and many manufacturers began to work hard to find more suitable alternatives.
In addition, as the power of fast charging increasing, the size of the fast charging head becomes larger, which is very inconvenient to carry; some high-power chargers are prone to cause heat of charger after long-term charging. Therefore, it is more urgent to find new alternative materials .
Gallium nitride (GaN) is called the third generation semiconductor material. Its performance is improved exponentially, and it is more suitable for high-power devices than silicon, with smaller size and higher power density. The frequency of GaN chips is much higher after compared with silicon. Which material can reduce the volume of internal transformers and other original components effectively. At the same time, the excellent heat radiation performance also makes the layout of internal original components more precise, and finally solves the contradiction between charging rate and portability. Obviously, GaN is the replacement material we are looking for.
Well know about the characteristics of their materials, the difference between GaN chargers and other normal chargers is self-evident. GaN chargers are smaller at the same power and have better heat dissipation, making it easy to achieve high power in a small size.
