Disassembly report: Shangxun 230W gallium nitride charger

2021-12-01

For light and thin laptop products, at present, chargers within 100 watts have been able to meet the charging demand. With the support of gallium nitride technology, the volume of 100 watts fast charging has also been greatly optimized and the Portability has been greatly improved. However, for the performance book and game book with high performance, the charging power within 100 watts is obviously insufficient, and the high-power fast charging potential above 100 watts will double the volume and become very cumbersome.

As a third-party parts manufacturer, Shangxun has previously launched a variety of gallium nitride power adapters with a power of more than 100 watts, including a 120W gallium nitride power supply previously disassembled by the charging head network. Recently, Shangxun once again launched a gallium nitride power supply with an output power of up to 230W, and has obtained the national CCC certification. Thanks to the application of gallium nitride technology, the volume of this power supply is reduced by half compared with the power supply of traditional devices, reducing the burden for users' travel.

The following charging head network will share the disassembly of Shangxun 230W gallium nitride charger to see how the internal structure and materials of this product are.

For the traditional game book power supply, large bricks have always been the inherent impression left to users. Although they can meet the power consumption of the game book, the product volume is really a little difficult to accept, especially when you go out and carry it, which is very inconvenient. Shangxun 230W gallium nitride power adapter not only ensures the performance, but also greatly optimizes the volume, and the power density of the whole machine reaches 0.92w/cm ³， The portability of power accessories is improved.

In terms of performance, Shangxun 230W gallium nitride charger adopts the high-performance architecture of PFC + LLC, supports 100-240V wide voltage input, fixed 20V voltage output, and the nominal maximum output current can reach 11.5a, which can meet the charging needs of game books such as Lenovo Savior y7000p, and has obtained CCC certification with reliable quality.

In terms of materials, NXP tea2016aat + tea2095 full set of controller scheme is selected, with high chip integration and simple peripheral circuit. At the same time, four innoseco gallium nitride switches and a mepson silicon carbide diode are built to improve the performance of the whole machine. In terms of capacitance, the gallium nitride fast charging special capacitor filter pushed by Yongming is selected to provide stable output for notebook computers.
