The output is fixed at 1.8V, so you save two resistors and one feedback node. The 1A current rating gives headroom above a typical load.
ROHS3 compliant.
Yes. The input range of 2.3V to 6V covers single-cell Li-ion (3.0–4.2V) and two-cell alkaline. The synchronous rectifier keeps efficiency high at light loads, which extends battery run time.
The TPS62290 is a similar 2.25MHz synchronous buck but offers an adjustable output version. The TPS62293DRVR is fixed at 1.8V, which saves two feedback resistors. Both share the same package and pinout, so they are footprint-compatible — the choice comes down to whether you need a fixed rail or an adjustable one.
