Hardware M92t36 pin 6

[seidolino]

hey guys!

I checked the M92T36 a few days later and the 3,5V from PIN 6 are gone again I already tried 6 other M92T36, but PIN 6 hasn't got any volts. Any ideas what I can check/recheck? The replaced/added resistors look okay as far as I can tell.

thanks!

Hi there,

I appreciated if someone still looking for identify "ENXX" WLCSP 20pin BGA chip besides ALC5639.

I think the chip is not audio amp +DAC at all.
Because I removed the chip and check PCB pattern, I think it is definitely power rail...

So I guess the chip is RP602Z330C-E2-F by RICOH, a Buck-Boost DC/DC Converter.
RP602Z330C is starting from ENxx

I hope the information is useful for someone...
