LM3481: spec of transformer used in PMP20981

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

Paul
