The TPS62112MRSAREP is a synchronous buck converter from Texas Instruments that takes a 3.1 V to 17 V input and delivers a fixed 5 V output at up to 1.5 A.
The synchronous rectifier (integrated FETs) keeps efficiency up across that range, reducing the thermal burden on the exposed pad.
Listed as Active by TI.
Both share the same base number TPS62112 and the same buck converter core. Electrical specs are identical; the choice is a logistics decision for the pick-and-place line.
