Part Number: TPS54327

Hi team,

Let me confirm the definition of the tss below. Is it the time from Vout=10% to Vout=90%? If no, please let me know the correct information.

And is there any limitation on C6 (Css)?

Best Regards,

Hayashi

HI Zhang,

Let me add another question.

Is there any data for Tdelay? (min, max, typ)

Customer must know the duration from VEN to exisitng Vout as below in min/typ/max in order for sequence.

Best regards,

Hayashi

Hi Hayashi

The SS time is the time Vout from 0% to 100%, the Td are not tested, You can let the customer check the time with the EVM, and I'll also check it with EVM and evaluate the Min/max value. thanks!
