Other Parts Discussed in Thread: AM3352
In the TPS65910Ax User's Guide for AM335x Processors (Rev. F) page 3 of 10, the diagram shows the SMPS and LDO connections to the AM335x. We are using the AM3352 in our current design.
TPS65901 AM335x
VDIG1 300mA (default 1.8V) -----> VDDSHVx
VAUX2 300mA (default 3.3V) ------> VDDSHVx
VMMC 300mA (default 3.3V) ------> VDDSHV
I understand the VDDSHVx is a dual voltage zone for VDDIO as either 1.8V or 3.3V. Only VDIG1 or VAUX2 is connected to VDDSHVx, not both. However, what is the actual pin connection(s) for VMMC?
With reference to the BeagleBone Black schematic, PCB revision B6, the PMIC is the TPS65271C and LDO4 (VDD_3V3A) is connected to all the VDDSHV pins.
Thanks,
Jim
