TLV62569: Sizing Inductor to keep out of power save mode

Part Number: TLV62569

Hi TI,

I have a voltage rail where I'd like to use the TLV62569, but I'm concerned about the power save mode creating noise in my system.  Section 9.3.1 shows that the device enters PSM when the inductor current becomes discontinuous, so it seems that as long as the inductor current is continuous, the device wouldn't enter a light load mode, correct?

For 3.3Vin, 1.35Vout, and 200mA Iload, how can I size my inductor to keep out of discontinuous / power save mode?

Thanks in advance,

Aaron
