Hi,
I'm using the TPS65295 in my design which doesn't need to support the S3 state. In this case, can the SLP_S4 and VTT_CNTL inputs be shorted and controlled be a single driving source to enable/disable the device? Also, the datasheet contains scope shots of VTT shutdown through the SLP_S4 input and through the VTT_CNTL input. Is this for information only? Because I am not aware of any requirements for shutdown sequencing of the DDR4 voltage rails per the JEDEC specification.
Thanks,
James
