P1V8 - FMC VADJ limitations
P1V8 is sourced from a 4A stage of IRPS5401, and is used for;
- EMMC I/O
- FLASH
- EEPROM
- MACID
- WATCHDOG
- SoC PSIO Bank 500
- SoC VCCO Bank 64, 66, 67 - 71
- SI53312
- LAN8331 via the LDO from IRPS5401
- FMC VADJ
there is a limit on FMC ADJ - around 1A or so.
- either power the FMC VADJ separately
- or add notes to explain the limitation, and add a fuse to VADJ for the FMC (probably the same fuse as the 12V FMC) (FMC consuming too much power on VADJ will create weird side effects owing to the other places this rail is used)
