Recently, Samsung launched a new 45W travel charger EP-T4510, according to the charging head network disassembly report, the charger applied the third generation of semiconductor gallium nitride fast charging technology, which marks another mobile phone giant in the consumer power field officially entered the gaN gallium nitride fast charging market, which played an important role in promoting the popularity of gallium nitride technology.
Samsung 45W Gallium Nitride Fast Charge has now been listed on the official mall, and the retail price is consistent with the previous generation of 45W chargers, which are 299 yuan. As Samsung's first gallium nitride fast charging accessory, the charger uses the high-frequency and high-efficiency characteristics of the third generation of semiconductors to achieve a miniaturized fuselage design, the whole machine size is only 43.5 × 63.7 × 28 mm, with the highest power density in Samsung chargers, compared with the previous generation of 45W fast chargers, the volume is reduced by 30%.
In terms of performance, it supports 100-240V~50/60Hz global wide voltage input, the output is compatible with USB PD3.0 PPS fast charging protocol, and has four fixed voltage levels of 5V3A, 9V3A, 15V3A, 20V2.25A, and 3.3-11V5A, 3.3-16V3A, 3.3-21V2.25A.
The charging head network further learned that Samsung's 45W Gallium nitride fast charger is manufactured by a Vietnamese foundry and has a custom GaNFast chip NV6014 built into nano-micro semiconductors. It can speed up charging for Samsung's newly released S22+, S22 Ultra, and S8 Tab tablets, and is also suitable for fast charging of all devices compatible with the USB PD protocol on the market.
summary
Gallium nitride fast charging technology has been very rapid development in the consumer power supply market in recent years, especially when the major hand /laptop brands have entered the market, the industry popularity of gallium nitride fast charging has been greatly improved, the stability has also been verified by the market for a long time, and has been highly recognized by first-line power supply factories and global well-known brands.
According to statistics, before Samsung entered the gallium nitride fast charge, Apple, Xiaomi, Huawei, OPPO, Meizu, Nubia, ZTE, Lenovo, Dell, Asus and most of the world's first-line terminal brands have introduced gallium nitride technology in power supply products and shipped as original accessories for some equipment. Although Samsung is the late player among many mobile phone brands, its industry significance is extraordinary, with the hegemony of global mobile phone sales, Samsung Gallium Nitride fast charger will soon spread throughout the global market.
Of course, we also have every reason to believe that 45W gaN fast charging is only the beginning of Samsung, and we look forward to the follow-up development of more high-power gallium nitride fast charging sources based on nano-micro GaNFast power chips to improve the consumer experience.
