Hello
I have a question about TPS65400. TPS65400 has SS pin for soft start.
SS1 capacitor on TPS65400 EVM is 4700pF. It's 0.67mS.
I would like to know MIN and MAX capaciotr value or any limitation.
Regards.,
Mitsuharu Iwasaki

Hi Eric,
Thak you for replying. Our customer is using 14nF for 2ms SS.
But they are trying robstness test. During power-up, DCDC output is connected 3A constant current.
Rail is power-up, but during power-up, switching wavefomr is like pulse skip not PWM.
I think that it's heavy test. But I'm not sure what constant current is better.
Could you tell me it?
