Power adapter refers to small portable electronic equipment and power supply equipment of electronic appliances.

It mainly converts the AC mains power into DC output to supply power to small electronic products such as mobile phones, flat panels, liquid crystal displays and notebook computers.

Take mobile phone fast charging as an example. Today, our mobile phones are becoming more and more powerful. At the same time, the adapters for charging mobile phones are required to develop towards higher power and higher power density. And the high-frequency and high-efficiency characteristics of Gan just meet this requirement.

Compared with conventional Si MOSFETs, GaN has the following advantages:

1. Low QG / CISS: fast breaking speed; Fast switching speed, reducing switching loss;

2. 2. Low coss / QSS: fast opening and closing speed, high switching frequency, and reduced switching loss;

3. Qrr = 0: no reverse recovery loss (no body diode), reducing switching noise and better EMI performance;

4. Low RDSON: reduce conduction loss. These advantages of Gan make the adapter using Gan smaller in size and more efficient.
