Hello,

I want to set soft start time minimum as much as possible, because of sequence requirement.

Please advise if I can left open the SS terminal or need any capacitor at SS terminal.

Please let me known the minimum required capacitance in case of SS capacitor is needed.

Best Regards.

TPS65251 can't support SS pin open. we recommad set the minimum soft start time larger than 1ms, if you really need quick soft start time, please make sure the soft start time is larger than 0.5ms. thanks!
