Hi Ramesh,

the custom transformer is from Wurth Electronics. You may contact Swaroop for details on the design. We do not have the details of the transformer

Swaroop.Vaidyanath@we-online.com

If you would like just the electrical specifications that we sent to Wurth, we can provide those.

Thanks,

Robert

Hi ramesh,

Please find the initial electrical specs that were used for the PMP22056. we first built the isolated and surface mount version and then changed to TH and non-isolated. same electrical specs.

Hi Sarmad,

Thanks for The details.

My concern is space for my design. Isolated design would increase my design size, that's The reason I have choose non-isolated.

If possible please provide inductor details which used for 5v,0.55mA design given in this reference design.

Or if you can suggest any inductor value instead of transformer structure it would be useful for me.

If possible please provide those calculation details.

Thank you,

Hi ramesh,

these are the electrical specs used for the transformer. i only changed it to Through hole. i would advise you to use the same TH footprint i used on my non-isolated design PMP22056.

thanks.
