TPS23758: Power Transformer: LDT1018-50R from LinkCom

Tony Steinbock

Part Number: TPS23758

Hello TI-Team,

for a PoE-Application, we want to use the TPS23758 to create 5V from PoE. In the evaluation board circuit of the TPS23758 is the power transformer of the type "LDT1018-50R" from LinkCom. Can you offer a datasheet for this power transformator? On my research i cant find a datasheet from this part.

In this context, we are also looking for an alternative power transformer. Can you recommend another power transformator, as in the evaluation circuit used? Actually we tend to use a power transformator from WE:

Is this 5 volt power transformer useful in combination with the TPS23758 from your point of view?

Thanks for your help!

Greetings Tony.

The LDT1018-50R datasheet can be found online at

http://www.linkcom.com.tw/product.php?c=3&p=10&product=PowerMagnetics

We can also connect through the TI E2E messaging system and I can share LinkCom contact information with you. Look for that Friendship request shortly.

As for your secondary question, I will assign this thread to a member of our team better suited to reply.

Thank you for your interest in PoE solutions from Texas Instruments,

Thank you very much for your support and the link to the datasheet. In addition to my first post, i found this power transformer: https://katalog.we-online.de/pbs/datasheet/749119550.pdf

I think this part is more compareable with the LDT1018-50R. In general, i look for an alternativ part for the LDT1018-50R, which is available on the big distributors (Farnell, Digikey, Mouser, ...).
