TPS6591133 Inductor Lo(VDDCTRL) recommended Value

Other Parts Discussed in Thread: DM388, DM385

On Table 5.5 of the TPS6591133 datasheet the external component recommendation for Lo(VDDCTRL) is a 2.7 uH inductor (typical) (page 13).

On the DM388 reference design http://www.ti.com/tool/tmdxevm388 page 14 of the schematic shows a 1.5uH inductor L5 for this device. 



If a customer is implementing a DM385 design using the TPS6591133 would a 1.5uH or a 2.7uH device value be recommended?  Thank you,
