LM2733 boost circuit - inductor current requirements
The chip has a rated current of 1A, so that is the minimum switching current.
In the typical parameters, it is listed as 1.5A.
In the graphs describing switching current at different temperatures, it can go up to 1.65A.
So to choose safely, you should choose a inductor that has a saturation current rating of at least 1.65A. But it means that the inductance has already started to drop at that current, so you might as well choose an inductor with current rating of 1.65A or larger, so that the saturation current rating is even higher.
Typically, inductors with higher current rating also have lower ESR, which will make them heat less and thus it will make your design more efficient.
