LMZ31710 question on layout vs TPS84A20

Other Parts Discussed in Thread: TPS84A20, LMZ31710

Hello Team,

My customer uses the TPS84A20 on a board and they did not connect AGND and PGND of TPS84A20.  It was communicated at the time that for the TPS84A20 it is connected internally. Therefore, we connected PGND to board ground and made AGND an island.  They are looking to use the LMZ31710 going forward.  Can you please verify this is also the case for the LMZ31710?
