Hello all,
I have a custom design using the TPS65910A3 with a AM3352 configured exactly like the TMDSSK3358 eval kit. The system will power up fine using the power button. Now, when powering down, all of the pmic supplies shut down as expected except for the PMMC supply. It instead drops from 3.3V to 1.7V. What could possibly be allowing VMMC to remain at 1.7V. The VMMC supply is only used as an enable for other supplies.
Thanks,
Jeff
