PMP41063: question about L1/L3

Tsuyoshi Nogi

Part Number: PMP41063
Other Parts Discussed in Thread: UCC28730,

Tool/software:

Hi experts,

I'm promoting UCC28730 and ask the customer to refer PMP41063.

The customer notice the L1/L3 have 250VAC rated voltage.

That reference design input voltage reaches 1,000V input so it is out of rated voltage.

Are there any suitable reason to use 744821201/744821110?

Thanks and regrads,

Tsuyoshi

Hi Tsuyoshi,

we didn't test EMI for this board, we can by pass this part if necessary, or we can use some High voltage common mode power line choke for replacement, such as WE-CMB HV Common Mode Power Line Choke | Passive Components | Würth Elektronik Product Catalog

Hi Max,

Thank you for your comments!

Would you share any information about verification with >1000V choke? (except PMP41063)

Thanks and regards,

Tsuyoshi
