LMR60410: Sizing Inductor for Over-Current limits

Tool/software:

Hello,

We're designing with the LMR60410.  In the datasheet there are 2 over-current specifications:

• 2.6A max high side peak current limit
• 1.66A max low side valley current limit

Which value do I need to design the saturation current of the inductor? 

Thank you, Keith
