>Product News>Disassembly report: Lixun precision 65W 1a1c Gan fast charging charger
2021-07-12
Recently, the charging head network has obtained a 65W Gan fast charging charger lps-65ab DC from Lixun precision. The charger is equipped with 1a1c universal oil interface and supports 45W + 18W dual port fast charging to meet the demand of fast charging for pen phone at the same time. The most important thing is that as a GaN fast charging device, it adopts a brand new type of domestic Gan power device, which is from Shenzhen yuantuogaoke Semiconductor Co., Ltd. Now we will take a detailed disassembly of this charger to see the specific design of the product.
It is worth mentioning that Shenzhen YUANTUO high tech Semiconductor Co., Ltd. is a high-tech enterprise of the third generation of semiconductor power devices initiated by senior power device R & D personnel in April 2019 and jointly founded by more than ten domestic and foreign semiconductor industry elites. The company's products are mainly 650V Gan power devices, product design and performance have reached the international advanced level. We have overcome a series of technical problems, such as Gan epitaxial processing, packaging and testing process. YUANTUO hi tech is committed to building a double first-class domestic and international brand of China's power semiconductor and making contributions to the development of China's semiconductor industry.
Lixun precision's Gan fast charge adopts PC material white shell, and the overall style is very simple. As a well-known manufacturer, it must be for the convenience of customers to customize the appearance. The product is equipped with 1a1c interface, which can adapt to the new and old equipment, and is compatible with qc2.0/3.0, AFC, FCP and PD fast charging protocols. The C port has five groups of complete voltage ranges of 5v3a, 9v3a, 12v3a, 15v3a and 20v3.25a, which can well meet the fast charging requirements of mobile phones and laptops at the same time.
Through the disassembly of the charging head network, we know that PCBA module adopts several small boards in the layout, which optimizes the use of the internal space of the charger. The charger adopts the high frequency QR switching power supply scheme composed of Anson ncp1342, yt65n15a, MPs mp6908a and Infineon synchronous rectifier. The protocol chip adopts Weiquan wt6633p and tiandeyu fp6601q, cooperate with Nanxin sc8701 voltage regulator and Jiangsu Changjing switch tube, and the overall material is reliable.
