4KV power isolation

Bill Keith

Other Parts Discussed in Thread: UCC12050

Im looking for an isolation solution for power. The requirement is 4KV so the solution should be 4.5KV or 5KV. The power on the isolated side is about 100mA. What do you have for a controller and transformer? Temp rating is 0-70C

Thanks.

Hi Bill,

We need more information about the application/regulator. What is Vin range, Vout, (Iout=100mA)? Desired switching frequency? Do you have a power topology in mind?

Regards,

Eric

Bill,

Here ya go, these products are DC/DC converter modules that meet all the requirements you provided (100mA, 5kV isolation, integrated transformer):

5V in, 5V out, could probably live with 3.3V out, Iout ~100mA. This is for USB isolation

The UCC12050 product that Steve recommended seems perfect for your application.

It does seem to fit what i need but there is no stock anywhere so that doesn't help much either. Or at least I couldn't find any stock.

If you contact your local TI sales office they can help you purchase them. They will want some details about the end application: annual usage, etc.
