Hi Team,

I would like to know the maximum capacitor value of Soft start pin (CSS).

Could you please let us know if you have a recommended maximum capacitor value?

Hi Hide,

We don't have a specific limit to the capacitor value of Soft start pin (CSS). But if you use a very big Css, two things will happen:

1. Vo will increase very slowly.

2. If over current happens, IC can't hiccup directly, because it need time to discharge Css.
