The future of gallium nitride charger

As the screen of electronic products becomes larger and larger, the power of the charger also increases, especially for high-power fast charging appliances, the use of traditional power switch can not change the status quo of the charger.

GaN technology can do it because it is the fastest power switching device in the world and can maintain high efficiency level in the case of high speed switching . It can be applied to smaller components and can be used to reduce the size of the charger. For example, the current typical 45W adapter design can be made 25W or smaller.

Gallium nitride charger has attracted the attention of the world. The high speed, high frequency and high efficiency make the high-power USB PD charger no longer a burly brick. The compact size can realize the high-power output, and it is smaller and lighter than the original 30W charger made by APPLE.

Put the built-in gallium nitride charger side by side with the traditional charger, the output power of the built-in gallium nitride charger reaches 27W, and the output power of the APPLE USB-C charger is 30W. The power difference between the two is not much, but the volume is completely different. The size of the built-in gallium nitride charger is 40% smaller than that of the Apple charger.

According to incomplete statistics, as of October 23, 2018, there are 52 types of mobile phones supporting USB PD fast charge on the market. Almost all mainstream mobile phone manufacturers have incorporated USB PD fast charge protocol into the charging configuration of mobile phones, including Apple, Huawei, Xiaomi, Samsung and other first-line brands.

From the perspective layout of major mobile phone manufacturers and original chip manufacturers, USB PD fast charge will become the current mobile phone, game console, laptop and other electronic devices preferred charging scheme, and USB Type-C will also become the only interface between electronic devices for power and data transmission in the next decade, USB PD fast charge protocol unified situation is coming.
