Love Tomb Style No. 246 - 100W full protocol fast charging module in the atmosphere of LM5176

Input voltage: 5V-30V

Output voltage: adaptive according to fast charging protocol

Maximum power: 100W (varies depending on protocol)

DCDC architecture: automatic voltage boosting and bucking

The input end is equipped with FS312 fast charging decoy adjustable type and C port

The output end is equipped with a power limit, which can be limited to multiple gears within 100W to match the input end.

The output is equipped with C+A

Equipped with PG LED indication

With EN enable control

First of all, I think this module is weird

When inputting 5V or 24V, the output is abnormal, the PG light flashes violently, and the inductor buzzes (the reason has been found out: I soldered a 47UH inductor instead of 4.7UH)

The output is normal when the input is around 12V, and after using the protocol chip

When outputting 5V, exceeding about 3.7A will cause the output to flicker, which may be due to the current limit of the chip.

The next version will remove the output PMOS and may replace the protocol IC.

(Second test) I changed the inductor to 22 2.2 6.8 but it still didn’t work properly. I felt that there was something wrong with the entire module. It is recommended not to use this solution.
