What is a gallium nitride（GaN） charger!

What is gallium nitride
Gallium Nitride (GaN) is a compound of nitrogen and gallium with specific semiconductor properties. It was used in light-emitting diodes in the early days. It belongs to the same periodic group of elements as commonly used silicon, and has high hardness, high melting point, high stability and strong stability. Gallium nitride material is an important semiconductor material for the development of microelectronic devices. It has the characteristics of wide band gap and high thermal conductivity. It can be used in chargers and can be adapted to small transformers and high-power devices, with high charging efficiency.

2.the advantages and disadvantages of GaN chargers
Advantages: small size, safe
Compared with ordinary semiconductor silicon materials, gallium nitride has a wider band gap and better thermal conductivity, and can match smaller transformers and high-power inductors, so gallium nitride chargers have the advantages of small size, high efficiency, and safety. . In recent flagship mobile phones and tablets, in order to achieve faster charging speed, the charger power is relatively large, and 40W50W chargers are very common. Greater charging power means that the size of the charger is also getting larger, and the heat is serious.
After switching to gallium nitride technology, the size of the charger can be greatly reduced and it is very portable. At the same time, the gallium nitride charger can also maintain high-efficiency and low-temperature working conditions, with better safety.

Disadvantage: high cost
The main disadvantage of GaN chargers is their high cost. As a new third-generation compound, gallium nitride has high requirements for the synthesis environment. In terms of manufacturing process, gallium nitride has no liquid state and cannot use the traditional Czochralski method of single crystal silicon to pull out single crystals. It is synthesized purely by gas reaction. It takes more than 1000 degrees to heat metal gallium in the airflow for half an hour to form powdered gallium nitride, so the cost of gallium nitride chargers is higher, and the price of corresponding gallium nitride chargers on the market is also higher than that of traditional chargers.
