Disassembly report: Xulian 68W 1a1c dual port fast charging gallium nitride charger

2021-11-27

Recently, the charging head network has obtained a gallium nitride fast charging charger from XuLian Information Technology Co., Ltd. the charger is designed based on the gallium nitride chip dxe65h015f080 of Chengdu nitrogen silicon technology Co., Ltd. to realize the national production of the scheme. The charger is equipped with 1a1c dual output interface, which supports rapid charging of laptop and mobile phone at the same time, with a total power of 68W. Let's disassemble this charger in detail and take a look at the specific design of the product.

Xulian 68W gallium nitride fast charging charger adopts block shape design. With the support of gallium nitride chip dxe65h015f080 of nitrogen silicon technology, the overall size is 55 * 55 * 30MM. In addition, it is equipped with foldable pins to meet the portable needs of users. The charger has passed FCC and UL safety certification, with excellent quality, safety and reliability. It is equipped with 1a1c interface and supports 18W + 50W output strategy to meet the rapid charging of two devices at the same time, and the practicability is also guaranteed.

According to the disassembly of the charging head network, the charger adopts Nanxin sc3022c + sc3503 high-frequency QR switching power supply scheme, together with nitrogen silicon technology dxe65h015f080 gallium nitride power device and vian synchronous rectifier. Both DC-DC circuits adopt Zhirong sw3516h scheme. Kongsheng electrolytic capacitor and solid-state capacitors of wanjingyuan and emerald are used for input and output filtering, and the overall material is solid and reliable.
