TPS53622: Question about differences between TPS53622 and TPS53622A

Part Number:TPS53622

Why is there no datasheet for TPS53622 on digikey, mouser, and avnet?  Other parts in the TPS536xx line have full datasheets.  Are you discouraging this part in new designs?

It's on my list of most suitable TPS536xx parts for a current design.

Thank you,

Dan
