BQ24295: Inductor Selection

Part Number: BQ24295

Hi,

Is it a hard requirement to go with a 2.2uH inductor for the charger? 

The schematic diagram on the datasheet shows 2.2uH, but the inductor selection section doesn't provide any guidance regarding deviation from 2.2uH.  It seems that a 1uH inductor will still provide acceptable ripple, and has better Isat.  But not sure if this will generate an AC loop issue.  The customer will only be using this inductor in Buck mode (charging the battery) and not in boosting.  That may impact whether or not a 1uH can be used. 

Thanks,

Chuchen
