Original question:

TPS2491: Please review design calculations and schematics

TPS2491: Soft start and MOSFET thermal resistance

I have updated the design calculation for lower load current and soft start. Could you kindly review it? 

Estimated MOSFET thermal resistance is on the higher side. Do you recommend changing the MOSFET?
