Hi,

What is the part number of the transformer? I'd like to order some and build PMP4484 to test out the application.

Hi Robert,

Thanks for the update.

I was looking into the datasheet of G095024LF provided by GCI, but the footprint and the inductance value of the transformer don't seem to match the info on PMP4484.

G095024LF (provided by GCI): 100uH, size 31.5mm x 31.5mm

EDR3909, PC95 (found that part from another TI Forum thread): 475uH, 15mm x 55mm

Can you please help verify the transformer T1 info?

Thanks,

Hi Harry,

So sorry for the trouble here, I mistyped the design number, so that transformer from GCI is actually for PMP4844, not PMP4484 that you asked about.

The correct part is the one that you referenced from the previous thread. Again, sorry for my mistake.

Thanks,

Robert

Hi Robert,

Thanks for the clarification. Unfortunately, I wasn't able to find/order the EDR3909, PC95 anywhere in the market. Any thought where I might be able to find and order them? If not, do you have any alternative part for that transformer?

Thanks,
