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

2024-09-11

Charging head network also got a 65W gallium nitride charger launched by huakesheng. This charger is configured with 2c1a interface, but both usb-c ports support 65W output and blind plug use. At the same time, it has 3.3-11v 3A PPS fast charge, which also has good fast charge effect on mainstream Android phones.

This charger supports 45+20w fast charging output when it is dual port output. It can also provide fast charging for mobile phones while charging the computer, which is convenient to use. Next, let's take apart this huakesheng 65W gallium nitride fast charge to see which scheme is selected internally.

The 65W 2c1a gallium nitride fast charging of huakesheng adopts a long shape, and outputs two usb-c ports to support power blind plug-in and 33W PPS fast charging output, which can meet the fast charging requirements of mainstream Android phones. When the two ports are used at the same time, it is 45+20w power distribution, and supports the rapid charging of mobile phones and notebooks at the same time. The addition of usb-a port is compatible with the charging of traditional devices. In general, the compatibility is very good.

According to the disassembly of charging head network, this gallium nitride charger of huakesheng adopts the sealed gallium nitride scheme of Nanxin, and uses Nanxin sc3057 sealed gallium nitride chip with sc3503 synchronous rectifier controller to form a switching power supply with fixed voltage output. The output protocol chip uses British chipset ip2723t for one of the usb-c step-down control, and ip2726 for usb-c and usb-a step-down control. Both of the two step-down circuits use Xintan micro ndp1460 to step down.

Two PCBs are welded inside the charger to improve space utilization. The internal step-down converter and gallium nitride sealed chip cover the heat sink for heat dissipation, and the output uses solid-state capacitor filtering. The overall workmanship is solid.
