LM3481: PMP20981 schematic

Paul Sayles

Part Number: LM3481

I have the same question as was previously asked but never answered regarding the reference design transformer part number PA4191NL. Can you supply any generic specs on this part? Inductance? Current ratings?

Hi Paul,

Thank you for posting. Could you tell which ref design? There are different circuit designed by different engineers. If you tell the ref design number, I may be able to get the info for you.

Thanks,

Hi Paul,

Let me check with my colleague. The transformer seems being made by Pulse Electronics, and it may not be fully released yet, because I cannot find the info from their website. Stay tuned.

Thanks,

Youhao
