Dear Team,

Here is Kevin from Delta Taiwan team.

Is it possible to make the maximum 5.6ms soft start time longer?

Hi Kevin

The soft-start is only selectable to the four values based on Rmode selected. So, it is not possible to make soft start time longer than 5.6ms with the TPS53355.

5.6ms is a pretty slow soft-start. What is requiring a larger soft start time?

Regards,

Gerold
