Hello, I start to repair this sort of board, but I’m lost. Bye the old 2 mosfets + charging chip + 3v-5v…
I can’t « read » this board (Asus UX425 but I saw this in others boards).
I see :
In GREEN : 2 diodes for 2 power USB-C ways (I removed one diode)
BLUE : 2 thunderbolt controllers
RED : PD controller CYPD (for negociate the voltage with devices plugged in USB-C)
Comment : in order to appearence, I see thunderbolt controller « and after » PD controller guess. I guess (I hope) those 2 controllers are in parallele, for separate power and signal lines ?
YELLOW : ? I can’t understand the parallel way ? compare ?
ORANGE : outputs for voltages created ? 5v 3v ? or 20 v ?
(I saw a BQ chip on the board)
Thanks
