TPS543C20A: Soft-Start Time Variation

Shinichi Yokota

Part Number: TPS543C20A

Hello,

How much does TPS543C20A's soft-start time vary for a given R_SS value over process, voltages, and temperatures?

This thread gives an answer for R_SS = Open, but I'd like know about its variation for the R_SS values listed on Table 1 in the data sheet.
