[Video] Wanfen UP suspected of stealing platform IP6518 module design data leaked

2021-9-6: As mentioned earlier, the cover of this project adopts the cover submitted by the "original" UP owner at station B, but was later persuaded to change the cover. Please don't misunderstand that I imposed a label!

First of all, IP6518 is a fast charging chip with an output power of 45W.

Built-in power reduction circuit and identification circuit, only simple external resistors, capacitors and inductors are needed to build a powerful fast charging solution

The input voltage is optimal between 12-30V

The output can be easily changed within 20V according to the fast charging protocol, and the maximum output current is 5A (all based on 45W maximum power)

Supported protocols include QC FCP SCP SFCP PD, etc. In short, most of them can be used.

Its protocol pins support A+C configuration, and a conflict-type design is used here.

The main reason is that this chip is highly integrated, which makes peripheral layout very difficult, but I never imagined that this kind of layout would be copied and posted in Bilibili videos and openly labeled as homemade.

First of all, I don’t think the original idea of ​​the copper pillar stacking module was the first to come to mind. I may have some reference.

What I find confusing is as follows:

0: [ Major premise] The peripheral specifications used by the two are almost the same
1: The fuse and USB-A socket are the same model

2: The two LEDs of the original work are placed backwards, and the latter one is also placed backwards.

3:

Apour's output LED current limiting resistor has the same number as the original current limiting resistor.

4: The discharge resistor numbers of the two are the same.

5: The inductor wiring should be the same

6: RC peak clipping peripheral labels are consistent

7: The VIN and APOUR on the other side of the chip are not correctly connected to the input.

It just so happened that there was no link in the schematic diagram of the original work (as shown below). The PCB of the original work was later connected to APOUR's changes based on the original work:
deleting an electrolytic, adding an MLCC and DC socket. Exchange the capacitors on both sides of the current sensing resistor.

By the way, I added a C port and connected the chip.

By the way, it is recommended not to do this for the LX network of the inductor, as it will affect the loop.

I hope everyone will support open source players and respect open source,
