TPS23754EVM-420: Transformer parameter

Fandy

Part Number: TPS23754EVM-420

Hello,

Please provides the detail parameter of the transformer used in the TPS23754EVM-420, my customer need provide it to transformer factory, thanks.

by the way, if the transformer's size is not suitable to customer, example change the transformer bobbin, and how to design the transformer ? the datasheet and EVM not describe how to design transformer.

Hello,

Which parameters do you mean? Here is a link to the transformer datasheet: https://www.coilcraft.com/pdfs/poe300.pdf

We do not include how to pick a transformer for a design because that is beyond the scope of our datasheet. The IC can be used in multiple topologies, and to include how to design each component for each topology for each IC would be beyond what the scope of our datasheet provides.

If you are unsure, try to find a transformer with similar inductance, leakage inductance, DCR, and output voltage.

Regards,

Michael Pahl

Hi Michael,

parameter like magnetic core,framework, wire diameter, winding number,

turns ratio and inductor has been provided in T2 POE300F datasheet,but T3 PA0184lack of much parameter in datasheet.

Hello Fandy,

The best source for that information will be the transformer manufacturer. I sent you a connect request so that we can talk further in private messenger. Or, if you have your own methods / resources for contacting the transformer manufacturer I would suggest beginning that process. Thank you!

Regards,

Michael Pahl
