Compared with the continuous upgrading of mobile phone tablets, accessories chargers have been less popular. However, recently, a new technology gallium nitride has attracted a wave of heat for chargers. Gallium nitride chargers are rapidly applied by manufacturers due to their small size and high efficiency. So what is gallium nitride? What's the difference between gallium nitride charger and other chargers?

1、 What is gallium nitride

Gan is a kind of nitrogen and gallium compound, which has the conductor characteristics. It was used in light emitting diodes in the early stage. It belongs to the same periodic group as the silicon, and has high hardness and high melting point and high stability. Gallium nitride is an important semiconductor material for the development of microelectronics. It has the characteristics of wide band gap and high thermal conductivity. It can be used in charger with small transformer and high power device, and the charging efficiency is high.

2、 Advantages and disadvantages of Gan charger

Advantages: small size, safety

Compared with ordinary semiconductor silicon materials, GaN has wider band gap and better thermal conductivity, and can match smaller transformers and high-power inductors. Therefore, Gan charger has the advantages of small size, high efficiency and more safety. Recently, in order to achieve faster charging speed, the flagship mobile phone tablet charger power is relatively large, 40w50w charger is very common. Larger charging power means that the size of the charger is also getting bigger, and the heating is serious.

The size of the charger can be greatly reduced and portable after using gallium nitride technology. Meanwhile, the charger can keep high efficiency and low temperature working state, and the safety is better.
