2021-12-02
Recently, the charging head network has obtained a sicgecs 65W gallium nitride super flash charge. The square shaped body is equipped with folding national standard pins, which makes it very portable. Secondly, the charger is equipped with 1c1a dual output interface, which supports fast charging of pen and mobile phone 45W + 18W at the same time. For people who often travel abroad, carrying such a charger will be very convenient and more efficient.
Sicgecs gallium nitride super flash charge is small and portable, supports fast charging of dual devices at the same time, and the maximum output power is 65W, which is also the mainstream level. The performance of the product is also very good. It supports all mainstream fast charging protocols such as QC, AFC, FCP, SCP, pe2.0, pd3.0 and PPS, has complete voltage gears of 5-20v, supports fast charging of 3.3-21v3.25a PPS, and is well compatible with most brand equipment on the market.
The charging head network learned through disassembly that the main control chip of the charger switching power supply adopts sc3021c of Nanxin semiconductor, a well-known manufacturer in the industry, and adopts a proprietary Gan direct drive design, eliminating external drivers or discrete drivers, and no complex power supply circuit.
It can be seen from the front and back of the charger module that the periphery of the switching power supply circuit designed based on Nanxin sc3021c is very simple, and the power supply capacitor is no longer needed. It not only makes it easier to design a charger, but also helps to reduce the system cost.
In addition, this charging head also adopts Gan systems gs-065-011-1-l gallium nitride power tube. Zhirong sw2303 and sw3521 control 1c1a dual port output voltage respectively. Wanjingyuan and Yubang brand capacitors are used for input and output filtering, and the overall material is reliable.
