Dear team,

My customer wants to use our 28070 to act as boost converter. The input is 200V and the output is 800V, and the output power is 35kW-50kW. Could you please tell me how to design our device to meet the customer's requirement?

Thanks & Best Regards,

Sherry

Hi, Sherry

UCC28070 is not able to support DC input voltage, it is only fit for AC input voltage.

I recommended UCC28180 to support your request.

Hi Yunfeng,

This device is not non-Q1 device. Do we have Q1 device for such application?

Thanks & Best Regards,

Sherry

Only UCC28180 can support the DC input, but it is non-Q1 device. So there is not suitable analog solution for your application.

You may need to consider digital solution.

If you are interested in digital solution, you may need to re-post to UCD3138.
