We believe that those who care about the mobile phone industry recently have noticed that "Gallium Nitride (GaN)" has appeared more frequently in the near future. Especially after Xiaomi released its first 65W gallium nitride fast charge charger, the term "gallium nitride" began to appear in the public's field of vision. So, what is the difference between a charger that introduces "gallium nitride (GaN)" and a traditional ordinary charger? Let’s talk today.

 

Different materials are the root of all differences

The basic material of a traditional ordinary charger is silicon, which is also a very important material in the electronics industry. However, as the limits of silicon are gradually approaching, the development of silicon has reached a certain bottleneck, and many manufacturers have begun to work hard to find more suitable substitutes.

 

In addition, with the increase of the fast charging power, the fast charging head is larger, and it is very inconvenient to carry; some high-power chargers can easily cause the charging hair to heat for a long time; therefore, it is more urgent to find new alternative materials .

 

 

Gallium nitride (GaN) is called the third-generation semiconductor material. Compared with silicon, its performance is doubled, and it is more suitable for high-power devices than silicon, with smaller volume and greater power density. The frequency of gallium nitride chips is much higher than that of silicon, which effectively reduces the volume of internal transformers and other original components. At the same time, the excellent heat dissipation performance also allows the internal components to be arranged more precisely, which finally perfectly solves the contradiction between charging rate and portability. Obviously, gallium nitride is the alternative material we are looking for.

 

 

Knowing the characteristics of their respective materials, the difference between a gallium nitride charger and an ordinary charger is self-evident. The gallium nitride charger is smaller in size with the same power, and has better heat dissipation, which makes it easy to achieve small size and high power.

 

 

Since gallium nitride is so good? Why not use it earlier?

 

The reason is simple: GaN technology was not mature before, and the cost was relatively higher! The main cost of gallium nitride chargers comes from MOS power chips. Expensive raw materials have directly led to the high price of consumer-grade GaN chargers. At present, there are basically more than one hundred gallium nitride chargers on the market. However, as more and more manufacturers participate, it is believed that the technology will become more and more mature, and the cost reduction is only a matter of time.

 

In terms of the charging protocol, the GaN charging head currently uses the PD protocol as the mainstay, and can quickly charge devices that support this protocol, including MacBook (and other C-mount notebooks), iPad Pro, iPhone, Switch and other devices. With the blessing of gallium nitride, it is believed that the fast charging power of smart phones is expected to reach new heights.

 

 

As users’ demand for charger versatility and portability increases, the GaN fast charging market will grow rapidly in the future. According to data from CITIC Securities, the global GaN charger market is expected to reach 2.3 billion yuan in 2020, and it will rapidly rise to 63.8 billion yuan, a five-year compound annual growth rate of 94%.

 

In terms of the entire consumer electronics industry, GaN has already received attention and investment in mainstream consumer electronics manufacturers around the world, and GaN is also rapidly exploding with chargers. In terms of overall performance and cost, GaN is also expected to become the mainstream choice for fast charging devices in the consumer electronics field in the future.
