This is a single-output, positive-configuration part with synchronous rectification built in.
The 20-DSBGA is a wafer-level chip-scale package. The part reflows directly onto the board with no leads to inspect.
It is ROHS3 compliant. No LTB risk for new designs.
The switch current rating is 3.5 A. In practice, the continuous output current depends on the input-to-output voltage ratio and thermal conditions, but the part is designed for loads up to about 3 A in step-down mode.
The LM53625LQURNLRQ1 is a different class of part — a 2.1 MHz step-down (buck) only, with a 2.5 A output and automotive qualification. It is not a functional replacement for a buck-boost. The closest functional second-source within TI's portfolio is the TPS63025 in a QFN package, which shares the same buck-boost core but comes in a different footprint. No direct pin-compatible second source is listed.
Yes, it is ROHS3 compliant.
