Hello,

Thank you for your question. Here is our answer:

- Yes, InnoSwitch3-CP family can deliver 4 A output.
-If you are talking about ILim mode, there are two modes available which is determined based on the BPP capacitor. For the Standard ILim Mode, use 0.47 uF capacitor and for the Increased ILim Mode use 4.7 uF capacitor.

Hope this answers your question. If you still have any, please feel free to comment.

Thanks,
