Szukam zamiennika dla tytułowego SY8386RHC.
Jest to sterownik z wyjściem 1,8V.
Jeśli dobrze rozumiem to mogę go zastąpić SY8386BRHC?!?
Mowa o płycie LA-J701P.

Hello!
No, the chip SY8386B is NOT a suitable replacement under any circumstances.

The original SY8386R is the chip for generating 1.8V power rail, while the SY8386B is for 3.3V power rail only.

A za cewką to nie jest jakiś dzielnik napięcia?
Przepraszam, może głupie pytanie ale mam braki w tym temacie :roll:
Wycinka schematu nie mogę dać bo mam na nim napisy producenta.

In case of the original chip SY8386R yes, but not with SY8386B.
The SY8386B has a fixed output voltage of 3.3V which can't be changed (there is not a feedback resistor divider).

The pins 8, 12 of these two chips has also completely different functions.
