Hi Peter,

The necessary suggestions (also mentioned in section 11 of of ISOW7842 datasheet) to avoid such an issue were provided to customer.

Do you see any issues in using ISOW or was it a general question?

Hi sir,

It is the general question.

Customer want to use ISOW7842, but he saw there were some issue discussion on E2E but no any answer for them.

They want to double-check again.

Thanks.

Hi Peter,

Thanks for the confirmation. We don't expect any specific issue with ISOW7842, it being an isolated DC/DC converter it will have similar benefits and challenges like any other isolated DC/DC converter.

I will go ahead and close this post but if you do have any further questions, you can reply back or create a new post. Thanks.

Regards,
