LM3481: spec of transformer used in PMP20981

Paul Antunes

Part Number: LM3481

Hi,

i'm looking for transformer spec designed on TI ref design http://www.ti.com/tool/PMP20981.

based on the BOM, part# PA4191NL (Pulse Engineering) => not found on the web nor Pulse website

Can you share the spec of transformer ? my customer would like to design isolated flyback 12V up to 48V for PoE PSE application (15W). TI design is good fit but now they need further information on the BOM to estimate total cost before moving forward.

thanks for your help

Hi
The responsible engineer is out of office now. He will reply by 4/23.
In general, we don't forward other company's datasheet if it is not released in public.

Hi Eric,

Understand your point but it has no sense for TI to release ref design based on parts not public. we want customer to duplicate our ref design, so they need the BOM and all datasheet.

looking forward to seeing reply from reponsible engineer.

regards,

Paul

Paul,
This issue has been taken care of offline. As Eric mentioned the best way to find the correct datasheet is to contact the manufacturer directly.
Thanks,
Garrett
