Disassembly report: Green link 65W 4C port Gan fast charging charger

Recently, ugreen launched a 65W Gan fast charging charger, which is small and portable with "tofu block" founder design, foldable pins and four usb-c interfaces. This is also the industry's first 65W 4C Gan fast charging, with advanced product design concept. The C1 and C2 ports support 18W fast charging, and the C3 and C4 ports support 65W fast charging. The single port output performance of the two groups of interfaces is completely consistent, and can be used for blind plug-in. Now let's share the disassembly of this charger with our little friends to see how its materials are made.

Previously, Greenlink also successively launched 18W PPS charger, MFI certified 18W PD fast charging charger, Greenlink 30W USB PD charger, 2a2c 48W intelligent charger, 65W USB PD Gan fast charging charger, 65W 3c1a Gan fast charging charger and other charging accessories to fully meet the needs of different consumers.

1、 Appearance of lvlian 65W Gan charger

The front of the box is printed with the appearance of the product, ugreen brand and product name in the upper left corner, and Gan x65w and the four major features logo in the bottom. On the back of the box are the product features, specifications and basic information of lvlian Technology Co., Ltd.

The packaging box adopts drawer type design, the inner part adopts hard paper tray to protect the product, and the front end is provided with handle for easy removal.

The charger is fixed in the groove.

The charger is made of PC flame retardant material and black shell. The front view is close to square, and the four end arc transition. The center of the charger is the brand logo of lvlian.

The charger is square and looks like a piece of tofu.

The front and back of the fuselage adopt laser texturing technology, which is scratch resistant and wear-resistant. At the same time, it increases the aesthetic feeling and hand feel, full of business atmosphere.

The parameter information of the product is marked on the shell of the input end

Model: cd225


Input: 100-240V ~ 50 / 60Hz 1.8A


USB-C1/C2:5V3A、9V2A、12V1.5A,18W Max

USB-C3/C4:5V3A、9V3A、12V3A、15V3A、20V3.25A,65W Max

Total output power: 65W

Manufacturer: Shenzhen Chengguo Electronics Co., Ltd

Producer: Shenzhen lvlian Technology Co., Ltd

The product has passed CCC certification.

The pin adopts a separate plastic module, and the foldable design makes the charger easy to carry without scratching other devices in the bag.

The four usb-c ports at the output end are all black rubber cores, and the white lines are circled and divided into two groups. The interface side is marked with sequence and power parameters, which is convenient for users to use differently.

The measured charger length is 64.92mm with vernier caliper.

The width is 64.95mm.

The output protocol of usb-c1 port is detected by using chargerlab power-z kt002. The display supports apple 2.4a, Samsung 5v2a, DCP, qc2.0 / 3.0, AFC, FCP, MTK PE + 2.0, pd3.0 and PPS.

PDO message shows that usb-c1 port also has four groups of fixed voltage gears: 5v3a, 9v2a, 12v1.5a, 15v1.2a, and two groups of PPS voltage gears: 3.3-5.9v3a and 3.3-11v1.65a.

Kt002 is used to detect the output protocol of usb-c2, and its supporting protocol is exactly the same as that of usb-c1. In addition, PDO message is the same as usb-c1 port. Usb-c1 and usb-c2 single port output performance is the same, support power blind plug.

2、 Disassembly of lvlian 65W Gan charger

Take apart the shell on the back of the fuselage. There is a protruding plastic fixed column on the shell. The components are covered with isolation plate and brass radiator. After removing the isolation plate, there is a heat sink in the middle area below. The heat sink is coated with silica gel to help heat conduction. Take out the charger, the input end is equipped with a small board, the pin is connected with the small board through the AC wire, the output end is welded with four small boards, and there is a black insulating board behind for primary isolation.

The other half of the fuselage shell is provided with an integrated isolation plate, which plays the role of isolation and fixation. Remove the front heat sink and isolation board of PCB board, glue and reinforce components such as transformer and capacitor. The back of PCB is also equipped with heat sink and isolation board.

Summary of dismantling charging head net

Lvlian 65W 4C port Gan fast charging charger has many compatible protocols, supports multiple fixed voltage levels and PPS voltage levels, and has a wide range of overall compatibility. Among them, C1 and C2 ports support 18W PD fast charging, C3 and C4 ports support 65W PD fast charging, and the two groups of interfaces also support power blind plug-in, which supports the fast charging requirements of mobile phones, tablets, laptops and other devices, so it is convenient to use.

Through the disassembly of the charging head network, we learned that the whole circuit of ugreen green link 65W 4C port Gan fast charging charger adopts switching power supply and four-way DC-DC architecture. The switching power supply is composed of PI high integrated main control chip sc1936c and hengtaike synchronous rectifier MOS, with constant voltage output. Zhirong sw3516h + Ruijun ruh4040m2 step-down output scheme is adopted for four DC-DC secondary step-down output.

In the design, the charger is square and compact, and the front and back of the charger are processed with laser texture technology to increase the hand feel and aesthetic feeling; The input end is equipped with foldable pins, and the output end is usb-c interface, but the identification is designed. The internal layout of the charger is neat and orderly, with isolation and heat dissipation treatment. In addition, the charger is equipped with multiple filter capacitors, so the output is pure, and the output end adopts the same design scheme. The whole product is portable and easy to use, strong performance, full of business style.
