boost converter current limiter

Is there such a thing as a boost converter current limiter? Like a boost CV CC (constant voltage constant current). I want to keep the output of my set of 6 AA batteries at 9V but limit the output current to about 300 mA.

Actually, I would prefer to set my output voltage to not go below 8V, but that seems like a buck-boost converter with current limiting would be needed... and that seems more like hen's teeth.


Maybe this chip comes close:

Ta! Not sure if "with switch current" means current limiting, but seems like the goer at first look! Short of killer drones, TI has all the good shniz built into mm^3 packages.

That converter doesn't have any programmable current limiting. You'll need to look for something else, or apply some external analog conditioning to the feedback signal.
