Now that we have understood the two circuits of the PCB board, let’s look at the back of the PCB board.
From the welding situation on the back of the PCB board, we can know that the back is also divided into two ways of welding, and the input interface, transformer and three USB-A interfaces are all sunken plate welding, which can reduce the thickness of the charger.
中间部分镂空,用来放置两个变压器,芯片焊接在PCB板的边缘。我们先来看左侧USB-C接口的AC-DC转换部分。
The main control chip model is SC1933C. This chip has built-in GaN power devices and belongs to PI's PowiGaN series. It is also the first GaN power product launched by PI. Thanks to the advantages of high frequency and low loss of gallium nitride power devices, the power density of the charger can be increased, the size and weight can be reduced, and it is easier to carry.
PI SC1933C 无需外部元件即可提供精确的恒压/恒流/恒功率输出,并且可以轻松与外部快充协议接口 IC 配合使用,因此适用于高效反激式设计。充电头网了解到,该芯片此前已用于……RAVPower 61W GaN USB PD 充电器,ANKER 30W GaN gallium nitride charger和ANKER 60W 氮化镓双 USB-C 端口充电器使用。

Summary of disassembly of charging head network
ANKER 3A1C 四口氮化镓桌面充电器采用阻燃PC材质外壳,顶面经太阳纹理处理,更显美观。四角和边缘均采用圆角过渡设计,整体造型紧凑,节省桌面空间。USB-A接口最大输出功率为12W,总输出功率可达20W。USB-C接口所在电路采用氮化镓(GaN)元件,输出功率高达45W。此外,USB-C接口支持Apple 2.4A和USB-DCP协议,以及QC2.0和QC3.0快充协议,兼容性强,可满足大多数电子产品的快充需求。
通过拆解,充电头网络发现,USB-C接口电路采用PI的SC1933C作为主控芯片,该芯片内置GaN功率器件,并采用赛普拉斯的CYPD3175作为辅助协议IC。USB-A电路则采用PI的INN3265C作为主控芯片,该芯片集成了控制器、开关管和辅助同步整流控制器,集成度很高。充电器内部的两个电路独立工作,互不影响,因此即使四个端口同时输出,也不用担心总功率下降,并且每个端口都具有过流保护功能。输出端还采用了固态电容滤波,以降低纹波,使输出更加稳定。
