Solid materials, anfrui 1a1c 63w PD fast charging charger deep disassembly
At present, 1a1c dual port charger is very popular with the majority of consumers, and the major businesses and brands have launched their own dual port chargers in order to occupy a place in the market. Recently, the charging head network got a 1a1c 63w USB PD fast charging charger from ifory. This charger is equipped with 1a1c dual output interface, in which the maximum output power of port a is 18W, the maximum output power of port C is 60W, and the total output is 63w, which can meet the daily fast charging demand. The following small make up to share with you the disassembly of this charger, to see how the material inside.
1、 Appearance of ifory 63w fast charging power adapter
The charger adopts light blue body shell as a whole. The front and back of the charger are bright surfaces. The paint baking process is very smooth, and a layer of plastic protective film is pasted to protect the charger from being scratched during transportation. The side of the charger is frosted. The four corners of the charger are curved transition, and the ifory brand logo is concave printed in the center of the front.
The input end is equipped with foldable GB pin, which can be folded and put freely, and is easy to carry, and will not scratch other electronic products in the backpack.
Product information is marked on the shell of input end: ifory 63w fast charging power adapter model: 191101ls / N: 191101l9l6000065 input: 110-240V ~ 50 / 60Hz 1.8ausb-c single port output: 5V / 3a, 9V / 3a, 12V / 3a, 15V / 3a, 20V / 3A (60W max) usb-a single port output: 5V / 3a, 9V / 2a, 12V / 1.5A (18W max) dual port simultaneous output (63w max) usb-c: 5V / 3a, 9V / 3a, 12V / 3a, 15V / 3a 20V / 2.25A usb-a: 5V / 3a, 9V / 2a, 12V / 1.5A manufacturer: Kunshan liantao Electronics Co., Ltd. products have passed 3C certification and VI level energy efficiency certification.
The output end is equipped with 1a1c two output interfaces, usb-a interface with white rubber core, usb-c interface with black rubber core without copper exposure, and the lower end of the interface is gravure printed with ifory.
The thickness is larger than the diameter of a dollar coin.
The net weight is about 164g.
The output protocol of usb-a port is detected by using chargerlab power-z kt001. The display supports apple 2.4a and usb-dcp protocols, as well as qc2.0/3.0 and Samsung AFC fast charging protocols.
The output protocol of usb-c port is detected by using chargerlab power-z kt001, which shows that it supports usb-dcp protocol. In addition, no other protocol is detected.
The PDO message display of usb-c interface supports USB pd3.0 fast charging standard, and has five groups of fixed voltage gears: 5V / 3a, 9V / 3a, 12V / 3a, 15V / 3a and 20V / 3a.
2、 Disassembly of ifory 63w fast charging power adapter
The front shell of the charger is violently disassembled. There is a conical fixed column on the shell. The internal components of the charger are basically covered by metal heat sink. Glue is injected between the shell and the heat sink for fixing and auxiliary heat conduction. Insulating Marla tape is pasted on some parts of the heat sink for insulation protection.
Overlooking the whole charger, the transformer, electrolytic capacitor, solid-state capacitor and other components are also glued and fixed, and the primary switch tube beside the transformer is also fixed with a special radiator to help heat dissipation.
The plastic block at the input end is fixed with a clip, and there are two protruding metal shrapnel at the lower end, which are used to contact with the PCB to achieve the effect of power transmission.
After taking out the PCB, you can see that there is a metal heat sink on the small PCB next to the usb-a interface motherboard.
There is also an L-shaped heat sink on the back of PCB board, which is coated with glue to help heat conduction, and the edge is wrapped with Mala tape for insulation protection.
At the front end of PCB board, there are two pieces of metal sheet, fuse, common mode inductor, safety x capacitor, electrolytic capacitor and other components welded at the input end.
Close up of input sheet metal, through hole welding, full solder joint.
Li'e rt7880 is a USB type C power transmission (usb-c PD) and pulse width modulation buck boost controller with highly integrated functions and flexibility, which is suitable for the application of USB PD providers. The IC has an embedded arm Cortex-M0 microcontroller, which handles communication protocol, intelligent control of PWM converter, firmware based protection and various functions of customization. Can provide an excellent USB PD solution for a usb-pd vendor application with few external components and simple PCB layout. At the same time, Tongjia ld5763gs-u also has complete protection functions, such as OPP (over power protection), OVP (over voltage protection), fast oscp (output short circuit protection) and undervoltage / undervoltage protection, which can prevent the circuit from damaging under abnormal conditions. With frequency switching and soft drive functions, it can reduce noise and improve EMI. Its application fields include switching AC / DC adapter and battery charger open frame switching power supply.

Charging head network learned that Tongjia ld5763gs-u had been used by Lenovo ThinkPlus lipstick power supply, kunxing 30W USB PD PPS charger, Nubia red devil 30W USB PD PPS charger and zMi Zimi 65W 2c1a desktop PD fast charging charger. Summary of dismantling charging head net
The front and back of the 1a1c 63w fast charging charger is bright, the side body is frosted, the pins are flexible, foldable and easy to carry. Port a supports qc2.0/3.0 and Samsung AFC fast charging protocol, and supports maximum 18W fast charging output; The C port supports USB pd3.0 fast charging standard, and has five fixed voltage ranges of 5 / 9 / 12 / 15 / 20V, with a maximum output power of 60W. When the two ports are used at the same time, the output power of C port is still 45W, while the output of a port is not affected, 18W fast charging can still be carried out, and the total output is 63w, which can meet the daily fast charging demand.
We learned from the disassembly of charging head network that this charger uses chips from many famous manufacturers in the industry, such as Tongjia's PWM main control chip, Infineon's switch tube, MPs synchronous rectifier controller, Weiquan PD protocol chip wt6633p, and Lixi voltage regulator rt7880, and so on. The output of C port of charger is directly output after synchronous rectification by transformer, and the output of a port is output after voltage conversion by rt7880. Thanks to the use of voltage up and down circuit, the output voltage of a port is not limited by the output voltage of C port. In addition, the charger uses a large area of metal heat sink cover and a large number of glue injection heat conduction, the components are not only firmly fixed, but also the overall heat dissipation performance of the charger is very good.
