Finally, the A port supports QC2.0/3.0, FCP, SCP, VOOC/DASH/WARP, and PE2.0 fast charging protocol.
Second, Jiletang 45W three-in-one belt line car charging and dismantling
The top shell of the car is fixed with snaps, and the interior is equipped with a white light-guiding plastic shell.
Remove the car charging module.
The output cable weld is glued and reinforced.
The car charging module is composed of two long strips of small plates on both sides and a round plate at the output end, and the positive and negative metal sheets are connected and reinforced, and there are input and output filtering solid capacitors, inductors and other devices between them.
Split the three small plates apart.
The C-port mother board is equipped with a 1A1C dual-port output buck circuit on the small board, and the front is equipped with input and output filtering solid capacitors and inductors.
The other side features a buck protocol IC and an output protection tube.
The positive spring welds a red wire to reduce the resistance.
Patch fuse close-up.
The input filtered solid capacitor is 35V 100μF and protected by an insulated tube.
The 1A1C dual-port buck protocol IC adopts Ingenics IP6538, which is an integrated synchronous switching buck converter, supports 14 output fast charge protocols, and supports Type-C output and USB PD2.0, PD3.0 (PPS) protocol dual-port output SOC IC, providing a complete solution for car chargers, fast charge adapters, and smart row plugs.
IP6538 input voltage up to 32V, withstand voltage 40V, 8.2V automatic shutdown to prevent battery over discharge. The data pin supports overvoltage protection, and the IP6538 has a perfect protection function.
Injixin IP6538 supports dual USB Type-C, USB Type-C and USB A, or dual USB A output, integrated dual-port automatic plug-in detection function, use any one port alone can support fast charge output, when the dual port is used at the same time, the dual port output 5V.
Charging head network disassembly learned that the use of Yingji core IP6538 also has Jiletang 72W 3A2C multi-port car charging, Yubo 300W portable energy storage power supply, Jiletang 1A1C 20W fast charging mini car charging, WIZ 96W super charging station and other products.
Step-down inductive jacket insulated tube.
The output filtered solid capacitor comes from Yubang and is 16V 220μF.
The output protection tube uses the Gundman AD30K35D3, dual NMOS, withstand voltage 30V, for 1A1C interface output protection.
USB-C female close-up, sink via welding.
The round panel features a USB-A mother seat and LED indicators.
There are no components on the back of the board.
The LED is close-up.
Another small board also has a buck circuit for lightning line output buck and protocol identification. The front of the small board is also equipped with a filter capacitor and a buck inductor.
On the other side there is a buck protocol IC.
Input filtered solid capacitor close-up with 35V 68μF.
The buck protocol IC adopts Zhirong SW3522, which is a highly integrated multi-fast charging protocol charging chip, which integrates a 3.5A high-efficiency synchronous buck converter, supporting PPS, PD, QC, AFC, FCP, SFCP and other fast charging protocols and CC/CV modes. Only a small number of peripheral devices are required to form a complete high-performance multi-fast charging protocol charging solution.
Zhirong SW3522 data information.
Through disassembly, the charging head network found that Zhirong's fast charging chip can be widely used in chargers, car charging, mobile power, energy storage power and other fields, and has been adopted by dozens of products of well-known brands such as ASUS, Nubia, Leibai, Greenlink, lenovo and so on.
