Is it possible to get the schematic from T56?

Oleg_Skalskiy

There are questions about what should be in place u5
Yes, and in principle for future repairs in case of a short circuit

Oleg_Skalskiy

U5 1.2v but produces 3.3
And why is adj not installed. Why is it so hard to do.
U5 exactly at 1.2V?

Oleg_Skalskiy

Test is OK

Oleg_Skalskiy

And tell me the value of R29

Oleg_Skalskiy

R29 doesn't matter，This is only a discharge resistance of overcurrent protection signal.
it's ...

I have two parallel resistors
22kOm + 5.6kOm = 4.464kOm

Can be replaced by another value. And tell me which one?

Oleg_Skalskiy

This is the test screen. https://radikal.host/i/JXMTMK

VPP no j3 j4 j5 j6 j7 j8 no VPP is this normal?
VPP is 11.81 is this normal?
TEST normal

It doesn't matter.

Replaced with one 10kOm (0806)
Began to work better with EMMC.
How is this related?
and where can I find the schematic for the EMMC T56 adapter? MOORC adapter I want to fully adapt

Oleg_Skalskiy

Please, answer me!
We need a description of these elements marked in red

R1-R9 33 Ohm
Will they greatly change the work with emmc or is such a value allowed?

My Adapter
1. R1-R9    33 ohm               0806
2. C1 C2    10uf 50V             0806
3. C3         2.2uf 50V            0806
4. C4-C9    0.1uf 50V           0806
5. C10       15P 50V              0806
6. U4  LDO  XC6206-2.0V  SOT23
7. Between CLK and VCCQ I installed a 470 Ohm resistor (0806)
