Disassembly report: qcy 65W 2c1a gallium nitride fast charging charger

2021-08-07

Not long ago, qcy image, a large earphone manufacturer, launched a 65W gallium nitride charger, officially entering the gallium nitride fast charging market. On August 5, imago launched a new 65W gallium nitride fast charging charger, giving consumers a new choice.

Compared with the first model, the overall appearance design of the new 65W gallium nitride fast charging charger is basically the same. It is equipped with three 2c1a interfaces. Both C ports support 65W high-power fast charging with the same performance. It supports power blind plug and is easy to use. In addition, it also supports 45W + 20W charging strategy, which can meet the fast charging of MacBook and iPhone 12 at the same time.

The usb-a port supports the maximum 60W high-power fast charge and Huawei 22.5w super fast charge, which can meet the daily fast charge requirements of Huawei mobile phones. The three interfaces support multiple mainstream fast charging protocols on the market, with strong and practical performance. Now let's disassemble this gallium nitride charger in detail to see how the materials and workmanship are.

Qcy image's new 65W gallium nitride charger is the same as the first one in appearance. It adds an additional C port, which can charge up to three devices at the same time without waiting, so as to improve the charging efficiency. The overall output performance of the charger is also strong. It supports the full mainstream fast charging protocols of QC, AFC, FCP, SCP, pe2.0, pd3.0 and PPS. It has a complete voltage range of 5-20v and supports 3.3-21v3a PPS fast charging. It can be well compatible with most brand equipment on the market.

According to the disassembly of the charging head network, the charger adopts the high-frequency QR gallium nitride fast charging scheme of Nanxin semiconductor sc3021c + sc3503, combined with the domestic gallium nitride power chip innoseco inn650d02. The other two DC-DC circuits adopt Zhirong sw3516h scheme.

The charger adopts wanjingyuan electrolytic capacitor and solid-state capacitor for input and output filtering. PCBA module is covered with heat conduction pad and heat sink as a whole, components are glued and reinforced, and isolation plate is set between primary stages.
