Remove a 65W 2c1a Gan fast charging charger with built-in domestic controller

The charging head network learned from the supply chain that xinmaowei recently launched a high-performance synchronous rectifier controller lp35118v for GaN fast charging, and developed a set of 65W 2c1a Gan fast charging charger based on lp35118v, so as to show the performance of the chip. Next, we will disassemble the charger to see how it is designed.

1、 Appearance of 65W Gan charger

This charger adopts the long column shape design, and the surface of the body shell is treated with piano baking paint, so the whole charger is white and smooth.

The charger input is provided with foldable American pin.

The output top surface is equipped with 2c1a three interfaces, which are black rubber core and green rubber core respectively.

There is also an LED indicator on one side of the fuselage.

The length of charger body measured by vernier caliper is 77.28mm.

The width is 32.89mm.

The thickness is 36.85mm.

The intuitive feeling of the charger holding in your hand.

The weight is about 129G.

The output protocol of usb-c1 port is detected by using chargerlab power-z kt002. It shows that apple 2.4a, Samsung 5v2a, DCP protocol, qc2.0/3.0, AFC, FCP, SCP, pe2.0, pd3.0 and PPS are supported.

In addition, the PDO message shows that usb-c1 port has five fixed voltage gears, namely 5v3a, 9v3a, 12v3a, 15v3a, 20v3.25a, and 3.3-11v5a and 3.3-21v3a PPS voltage gears.

Using kt002 test, it is found that usb-c2 port supports apple 2.4a, Samsung 5v2a, DCP, QC, AFC, FCP, SCP, pe2.0 and pd3.0 protocols.

In addition, it has five fixed voltage gears, i.e. 5v3a, 9v3a, 12v3a, 15v3a and 20v3.25a.

Finally, usb-a port output protocol is detected, and the apple 2.4a, Samsung 5v2a, DCP, QC, AFC, FCP, SCP, pe2.0 protocols are supported.

iPhone Adapter


The charger usb-c1 port is used to charge MacBook Pro 16 of apple. The measured charging power is 20.08v 3.22a 64.6w, and 65W PD fast charging is successfully started.

In addition, usb-c2 port is used to charge. The same charging power is 64.6w, and 65W PD can be activated for fast charging.

Finally, the iPhone 12 Pro is charged with usb-c1 port, with charging power of 9.13v 2.53a 23.06w, and PPS fast charging is successfully started.

2、 Disassembly of 65W Gan charger

Disassemble the input end shell and attach heat conduction pad on the back of PCB board.

The front is covered with U-shaped brass fins and insulation plates.

Information of Weizhao vs3622de.

The charging head network has learned that vermemos is also used by dozens of power products such as wiz 96w USB PD fast charging super charging station, byaz 2c1a 65W Gan charger, Huawei 20W charge pump fast charging charger, vivo 33W flashcharge2.0 fast charging charger, millet original 30W fast charging charger, and purple meter 65W USB PD Mini charger.

Summary of dismantling charging head net

 

iPhone Charger Adapter


The charger body is long column, equipped with foldable pin and 2c1a interface, which supports QC, AFC, FCP, SCP, pe2.0, PD, PPS fast charging protocol, and has good compatibility. Both usb-c ports support maximum 65W fast charging, which can charge notebook, C1 port also supports PPS fast charging, which can meet the full speed charging demand of iPhone 12.

The charging head network is disassembled to understand that the switching power supply of this charger is composed of the Gan power chip g1n65r240pb of Ansenmei ncp1342 and gallium Future Technology Co., Ltd., and the core Mao micro lp35118v and the new power synchronous rectifier; The output end adopts smart melt sw3516h+ Ruijun ruh4040m2 to perform secondary step-down output. Based on the above design, the charger adopts three-stage layout structure, clear hierarchy, and small boards are set up for input and output to make full use of the internal space to reduce the product volume.
