2022-03-03

Elecom yilik is a well-known computer accessories company in Japan. Its keyboard and mouse products have won the BCN Award for many times. In recent years, yilik is also slowly involved in the fast charging power supply market. Previously, the charging head network has disassembled a 45W PD fast charging charger with its own usb-c cable.

Recently, charging head network has obtained a 45W charger from yilik, but it is designed based on gallium nitride black technology, equipped with folding pin and single usb-c interface, and supports PD3 0 general fast charging protocol. Now let's disassemble this charger in detail to see how the working materials are.

This model is equipped with 45W gallium fast charger, which is convenient to carry and conforms to the mainstream design. Although the maximum power of the charger is only 45W, it has 9V, 15V and 20V voltage gears and can charge iPhone 12 / 13, switch, laptop and other devices.

Through the disassembly of the charging head network, it is found that this charger is based on the architecture design of high-frequency QR switching power supply, adopts the PI sc1933c + AOS aon6220 switching power supply scheme, and Weiquan wt6636f protocol chip controls the output voltage of the interface. Using Zhibao electrolytic capacitor and solid-state capacitor for filtering, the overall material is still in line with the image of such a big brand as elecom and yilik.
