Switching frequency is fixed at 19 kHz. The inductor and output capacitor will need to be sized for that low frequency — expect larger magnetics.
This part is listed as Active — no end-of-life notice, no last-time-buy clock running. 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.
The switching frequency is fixed at 19 kHz.
