And the USB-A can support QC3.0, VOOC, SVOOC, Apple 2.4A, and DCP protocols.
Next, we took apart the charger from the input side.
Pry along the gap to open it up, the internal PCBA module is fixed by adhesives and cannot be taken out.
Then, use the cutting machine to cut off the plastic shell and take it out.
The PCBA module is connected by wires, and the components are fixed with adhesives.
The gaps between different components are filled with silicone adhesives for fixing and heat dissipation.
The length of the PCBA is about 56mm (2.20 inches).
The width is about 57mm (2.24 inches).
And the height is about 33mm (1.02 inches).
The power input wires are insulated with heat shrink tubing
Remove the heat sink covering the PCBA module. There is a thermal pad on the back of the PCBA module to dissipate heat for the bridge rectifier and the master control chip. The transformer dissipates heat through the heat sink, and foam is pasted at the position of the electrolytic capacitor.
The input fuse, common mode choke, safety X2 capacitor, filter capacitor and transformer are on the front of PCBA.
The bridge rectifier, two PI master control chips, SMD Y capacitors and synchronous rectifiers are on the back. Due to the use of PI's highly integrated master control chip, the charger circuit is quite streamlined.
The charger is equipped with two independent and symmetrical QR switching power supplies, allowing for a wide range of voltage output. The charger's output voltage is controlled by a protocol chip, which enables two ports to charge independently at 50W each. In instances where only one port is connected to a device, the protocol chip will automatically combine the two outputs to provide a single high-power output of 100W. Next, let's introduce every single component.
The input fuse is from WalterFuse. 3.15A 250V.
The first common mode choke is insulated with a white heat-shrinkable tubing.
The green NTC thermistor is from STE, used to suppress the inrush current when the charger is plugged in. Model is 5D-9M.
The safety X2 capacitor is also from STE. 0.1μF.
The second common mode choke is insulated with a black heat-shrinkable tubing.
The bridge rectifier is from Pingwei, model is MR810, and the thermal pad and silicone adhesive can enhance its heat dissipation performance. 8A 1000V.
And those four electrolytic capacitors are connected in parallel for input filtering and are from AiSHi RK series. 400V 33μF for each.
The differential mode choke is wrapped with heat-shrinkable tubing.
The master control chip utilized in this charger is the PI SC1738C, a custom-made model that could be interpreted as a high-powered adaptation of the InnoSwitch3-Pro power chip. It combines high-voltage switching, synchronous rectification, and FluxLink feedback functions into one digitally controlled cv/cc offline QR flyback switching IC. Specifically designed for use in efficient USB PD 3.0+PPS/QC adapters, it also supports the broader application of wide-voltage 50W adapters.
The SC1738C communicates with the protocol chip through the I2C interface and can dynamically adjust the output voltage and current. All protection functions can be configured.
Here is another SC1738C.
The two tiny electrolytic capacitors can power two master control chips. 50V 10μF for each.
The two transformers are insulated with yellow tape, and the ferrite core is ATQ23.7, wrapped with copper foil for shielding.
The charger utilizes SMD Y capacitors from the TRX SMD-Y2 series, specifically the TBY2101KB model. To enhance voltage resistance and increase safety ratings, two capacitors are connected in series, satisfying regulatory standards. TRX's SMD Y capacitors features in small size and light weight, and are very suitable for high-density power supply products such as GaN charger.
TRX focuses on the R&D, production and sales of passive components, with a registered capital of 100 million yuan. It has two types of capacitor brands: SMD TRX and DIP TY capacitors. TRX will devote itself to the research of ceramic materials in order to provide customers with more solutions.
ChargerLAB has discovered that the TRX SMD-Y2 capacitors are utilized not only in dozens of fast-charging products from recognized brands like Belkin, Anker, QCY, Senicc, Mcdodo, OPPO, Lenovo, Nubia, Baseus, ARUN, and DIVI, but also in other products such as the Eaglerise 40W LED power supply, and the Changhong 42-inch smart TV 42P3F internal power supply. All of these products have received high praise for their outstanding performance.
The other two SMD Y capacitors are also from TRX, but with a different model of TBY2221KB.
And the synchronous rectifier is from Infineon. 100V, 6mΩ for each. Model is BSC0805LS.
This synchronous rectifier is the same.
There're four solid capacitors and two USB ports on the output side.
The solid capacitor for output filtering utilized in the charger is made by PolyCap, specifically their VA high-voltage SMD capacitor. Two capacitors are connected in parallel.
Further analysis has shown that PolyCaps' products are extensively applied in various areas such as chargers, car chargers, wireless chargers, power banks, and portable power stations. They are also frequently integrated into many products from well-known brands, including OPPO, vivo, Xiaomi, Honor, Samsung, Huawei, Lenovo, ZMI, Nubia, Bull, ANKER, and others. These products have been highly recognized within the market.
The other two solid capacitors are the same.
After removing all plug-in components, we can now see the protocol chip.
It employs the INJOINIC IP2738 as its protocol chip, which governs control of both output ports. The IP2738 is a dual-channel protocol chip intended for fast charging applications ranging from 18W to 140W. It boasts independent feedback control alongside independent USB PD control, just like integrating two IP2736 chips into one. Its fast-charging specifications are indistinguishable from those of the IP2736. Additionally, the chip supports USB PD3.1 28V EPR levels, as well as PD3.0/PPS and a broad range of other fast-charging protocols with excellent compatibility.
The INJOINIC IP2738 contains four independent NMOS drivers capable of controlling multiple ports. Its functionality includes switching multiple VBUS MOSFETs for output port switching, parallel control of two power supplies, and dual independent overcurrent, overvoltage, and short-circuit protections to ensure safe usage.
The INJOINIC IP2738 has previously been used in Mcdodo 40W dual USB-C GaN charger, L Lab 140W 2C1A GaN charger, Anker 65W 2C1A 2-in-1 GaN charger, and UGREEN 140W 2C1A GaN charger. Other fast-charging chips from INJOINIC have also been adopted by major brands including Xiaomi, Huawei, and Samsung, and have received high recognition from customers for their performance and quality.
Two output VBUS MOSFETs marked with D40N03HL are from Pingwei, and the 5mΩ sampling resistor between them is used for output current detection.
The other two output VBUS MOSFETs are the same, used to control the two independent output circuits.
The USB-C connector is soldered on a separate small PCB and comes from CZT. The solder joints are sealed with adhesives to prevent any potential damage.
The TVS diode and thermistor are soldered on the back.
The plastic sheet inside the USB-C connector is red.
And the USB-A connector is insulated with white plastic shell.
The TVS diode and thermistor are also soldered on the back of this PCB.
The USB-A connector is equipped with a red plastic sheet and its positive and negative poles are deliberately designed to be wider than traditional one. Additionally, it includes auxiliary contacts located at the front specifically for detecting original cables.
