Part Number: TPS543A26T
Other Parts Discussed in Thread: TPS543A26

Tool/software:

I have an existing design with TPS543A26. The design uses Rmode = 2.21k, 174k and 2.74k to select soft-start time = 2ms and 4ms. Can I use TPS543A26T in place of TPS543A26 retaining the Rmode = 2.21k, 174k and 2.74k?

The above table 5.5 Electrical Characteristics of TPS543A26 and TPS543A26T shows different Rmsel value for TPS543A26 and TPS543A26T for the same soft-start time. Can you please confirm if the above table is correct? If yes, it is in contrary to Table 6-5. MSEL Pin Selection.
