Friends who use high-performance notebooks must be carrying a large brick power supply, and the weight of the whole power supply is close to one kilogram. This is not the backward technology of the manufacturer, but the high-performance notebook must use high-power power supply to meet the high-performance output of the notebook.

In order to cope with more application scenarios, USB PD3 1. The fast charging standard has been released, with a maximum output power of 240W, which can not only meet the charging needs of all laptops, but also be applied to electric vehicles, electric tools, security and other fields. Meanwhile, USB PD3 1 fast charging power supply will be able to achieve higher efficiency and smaller volume with the help of gallium nitride technology, and subvert the inherent image of traditional high-power power supply.

Recently, Juneng Chuangxin has launched a 240W gallium nitride power supply scheme. Eight gallium nitride devices are used in the whole power supply, which are respectively used for active bridge rectifier, PFC boost and LLC switching power supply. Thanks to the use of gallium nitride semiconductor and high-performance power supply architecture, the size of the power supply scheme is only 71.1 * 60 * 24.1mm, the weight of the scheme is 144.3g, and the power density at the board end reaches 2.33w/cm ³。

The volume of this 240W gallium nitride power supply scheme of Juneng Chuangxin is only 1 / 5 of that of the traditional brick power supply with the same power, and the volume advantage is very obvious. At the same time, the weight is only 1 / 5 of the traditional brick power supply with the same power, which is very convenient to carry and daily use. At the same time, the high efficiency brought by gallium nitride also reduces the heating of the power supply and greatly improves the use experience of the notebook.

Through the demonstration of the high-performance 240W gallium nitride power supply, we can see the application of the third generation semiconductor new technology and the significant reduction of the power supply volume. Through the application of the third generation semiconductor, the volume of the power adapter with a uniform weight of kg is reduced to a very easy to carry level.

By fully applying gallium nitride technology to the power supply, shaped core gallium nitride devices greatly reduce the power loss caused by traditional circuit architecture and traditional devices, and improve the working frequency of the power supply. Through the use of gallium nitride, the energy efficiency of power supply is improved, the volume is reduced, and the use experience of high-power adapters such as notebook power supply is improved.

Juneng Chuangxin is an enterprise engaged in the design and application scheme development of Gan power devices. Relying on its own technical team and its shaped energy crystal source, Juneng Chuangxin has mastered the industry-leading GaN material growth, device design and power scheme development technology for PD fast charging, wireless charging, smart appliances, 5g communication Provide pure domestic Gan power device products and technical solutions in cloud computing and other fields.
