In TPS40210-Q1 datasheet 7.3.4 : Current Sense Filtering, the suggested time constant is then: R × C = 0.1×Ton,Why the coefficient is 0.1? I hope get some theoretical explanation.
As the same the TI snubber design recommend : Fsnubber ≈ 0.1 Fring, here is the same coefficient 0.1. Is a same theoretical explanation between two formula?
