On February 9, 2020, the Samsung Galaxy S22 series was officially released, and the standard charger was cancelled in the entire series. It is worth mentioning that in order to meet the optional needs of Galaxy S22 Ultra and S22+ users for chargers, Samsung has also launched a new 45W Gallium nitride fast charger, model EP-T4510. Charging head network learned that this is Samsung's first gallium nitride fast charging accessories, which is based on nano-semiconductor GaNFast gallium nitride power chip development, to achieve the highest power density in Samsung charger, the product has the characteristics of small size, powerful and so on.
It is understood that the Samsung Galaxy S22 series includes a total of three products, Galaxy S22 supports a maximum of 25W fast charging, S22 Ultra and S22+ can support a maximum of 45W charging power.
As an optional accessory, the Samsung 45W GaN fast charger stands out among many accessories with its miniaturized design, its size is only 47.69 x 43.6 x 28.03 mm, the power density exceeds 1W/cm, and the volume is more than 30% smaller than Samsung's previous generation 45W charger. The use of nano-gaNFast gallium nitride power chips makes this charger lighter and more portable.
Charging head network disassembly learned that Samsung 45W GaN fast charger built-in a nano-micro customized gallium nitride power chip, model NV6014, the chip integrates gallium nitride power devices, drivers, protection circuits, nondestructive testing circuits and other functions.
GaN Gallium Nitride is a next-generation semiconductor technology that runs 20 times faster than conventional silicon chips. Nano-micro proprietary GaN power ICs integrate Gallium nitride devices, drive, control, and protection functions in a single SMT package. It is an easy-to-use, high-speed, high-performance "digital input, power output" module, compared with the earlier silicon solution, it can achieve up to 3 times the charging power at the same volume, and can save half the size and weight at the same power, saving up to 40%.
Gene Sheridan, CEO and co-founder of NanoMicro Semiconductor, said: "Samsung's consumers appreciate leading technologies with innovation, performance and quality excellence. "Samsung and Nanomicro are focusing on ensuring efficiency and sustainability while providing next-generation charging performance. Gallium nitride brings significant environmental benefits to the planet, and each nano-micro GaNFast gallium nitride power chip shipped can reduce CO2 emissions by 4 kg compared to traditional silicon solutions. ”
Charging head net summary
Nanomicro semiconductor is a leader in the gallium nitride power chip industry and the world's first company to successfully list with gallium nitride power chips as its core business, NASDAQ: NVTS.
After years of technical precipitation and market verification, NanoMicro semiconductor's GaNFast Gallium Nitride chip has been recognized by the industry for high reliability, and Nanomicro semiconductor has become a gaN supplier for mainstream mobile phone/laptop brand manufacturers on the market. The use of Samsung's 45W gallium nitride fast charging source is also another successful application of GaNFast gallium nitride chips after entering the supply chains of Apple, LG, Dell, Lenovo, Asus, Xiaomi, OPPO, vivo, realme and other manufacturers.
