Isolated DC-DC with 7,000V working voltage

Hello All,

One of my customer needs isolated power supply.

He once chose the ADUM4070 isolated DC/DC regulator with external transformer.

However, the ADUM4070 working DC voltage is 849V, its data sheet stated. He needs 7,000V DC working voltage isolated power supply.

Do you have any solution for 7,000 working DC voltage isolation power supply?

Best Regards,

    The products we have are all isolated data or power using chip scale transformers to provide the isolation.  As such, the isolation and the IC package both would need to withstand a working voltage of 7000V DC, which much more than the IC insulation and the creepage of the package could withstand, especially for a working voltage. Can you explain further the application need for such a high working voltage?
