TPS65217 Inductor for WLED circuit

Hi,

I got the following question from my customer.

They would like to shrink the size of the inductor for WLED than the inductor mentioned the Table.32 of the datasheet.

Could you let me know the range of inductance(uH), Ros(mΩ), Rated Current(A) to select the new one.

Regards,

Kuramochi,

I had to contact the designer to run simulations for the minimum inductance. He would like to know what ripple voltage customer can tolerate, and what is the value of output capacitance desired?
