Can you use an inductor not specified in the datasheet?

 

In general yes, although it is important to evaluate the characteristics of the
inductor considered. The DCR (DC resistance) will affect the efficiency as the
load current increases, while the core losses affect the efficiency at lower
load currents.

The saturation current must be sufficient to handle the load current plus the
ripple current due to charge/discharge cycle into the inductor. Please refer to
the ADIsimPower tool to select inductor base on detail design requirements.
