The base product number is TPS62801 — the YKAT suffix denotes the 6-DSBGA package and the tape-and-reel / cut-tape shipping format. If the board already routes for a DSBGA, the YKAT variant is the one.
Yes. The output can be set as adjustable from 0.8V to 1.55V using an external resistor divider, or ordered as a fixed 1.2V output variant. The YKAT suffix covers both options — verify the fixed-voltage marking when ordering against a specific BOM revision.
