GaN has brought many new opportunities to the smart, fast-charging field and has also entered several new application scenarios.

How to better develop smart, fast charging through GaN to improve charging efficiency and thus retain consumers has become a major challenge for most manufacturers in the industry.

Smart, fast charging into a new era, GaN technology to drive industry development

Smart, fast-charging technology has changed dramatically in the past few years, and almost every cell phone manufacturer has launched a cell phone that supports fast-charging technology. Since 2020, smartphones can achieve a 100W level of fast charging, and recent digital bloggers revealed that cell phone fast charging would soon enter the era of 200W fast charging!

However, the rapid development of intelligent, fast-charging technology and the market behind the fire is less GaN support. GaN and other third-generation power semiconductor technology have gradually become the focus of technological development in the industry. Under its influence, most of the smart, fast chargers on the market are developing towards miniaturization and high power. The user's demand is also developing towards the multi-port direction.

It is understood that GaN on the whole circuit volume compression, frequency increase, as well as its low switching losses are the advantages of silicon tubes can not be replaced, and GaN chargers can further effectively reduce the size, reduce heat and improve efficiency, and help improve energy efficiency and reduce energy waste. In the global scope, there are also several countries to GaN as the focus of scientific and technological research direction. The future GaN will have broader development prospects in intelligent, fast charging.

It is worth mentioning that the GaN chip solution is a fast-charging solution. The current fast charging solution interface is Type-C, plus the EU has reached a provisional agreement on the unified charger. The proposed legislation to force all smartphones in the next two years to use a common Type-C interface for charging, it is clear that GaN will contribute to the connector interface towards the Type-C interface to develop.

In addition, because GaN is an adapter for PD high-power fast charging, often with GaN chargers supporting the PD fast charging protocol has also ushered in many development opportunities in recent years, bringing new life to the field of smart, fast charging.

The USB-IF Association released the latest USB PD3.1 fast charging standard, which increases the extended power range, extending its maximum power from 100W to 240W.

For consumers, GaN can also make them get more convenience from it. For example, the common external power connector will become smaller and even have the opportunity to shrink completely into the body of the electronic product, making it more convenient to carry. In addition, GaN also allows smart, fast charging from cell phones, laptops and other traditional areas to expand to other applications such as defence, space, telecommunications infrastructure and satellite communications scenarios.

In the foreseeable future, GaN is expected to bring revolutionary changes to the field of smart, fast charging and good experiences to all aspects of people's lives.

Challenges and opportunities coexist. How should manufacturers use GaN?

Because the current cost of GaN will be more expensive than ordinary silicon devices, while the current industry chain is also temporarily not as mature as silicon, so GaN is still in a relatively preliminary stage of development. But the large demand for smart, fast charging and the need for its industry chain needs to mature as soon as possible. The connector also needs to withstand high currents and higher temperatures. How improve the charging efficiency under these conditions to retain consumers has become the most urgent task of the major manufacturers.

On the other hand, high power is no longer the only power point for fast charging. Manufacturers can no longer blindly pursue the fast charge. How to use GaN in fast charging application scenarios to maximize cell phone safety and extend battery life manufacturers are very "headache". These problems not only bring higher technical difficulty requirements for connector products but also give manufacturers needing to adapt to the new pattern a greater challenge and development opportunities.
