Switching frequency is fixed at 19 kHz. The inductor and output capacitor will need to be sized for that low frequency — expect larger magnetics.
It is RoHS non-compliant, so if your BOM requires lead-free solder, this part won't pass inspection.

The ADP1111ARZ is a surface-mount alternative with a 72 kHz switching frequency and buck-boost capability, but it requires a 2V minimum input and has a 0.4A output current limit. The ADP1612ARMZ-R7 is a higher-frequency (1.3 MHz) boost/SEPIC option for surface-mount designs, but it cannot step down.
Yes, the ADP1073AN is a buck-boost topology, so it can step up (boost) or step down (buck) the input voltage. The output is adjustable from 0.212V to 24V.
