WEBENCH® Tools/LM5180: WEBENCH don't work for LM5180

Part Number: LM5180

Tool/software: WEBENCH® Design Tools

Hi Team,

My customer would like to use WEBENCH for LM5180 evaluation but it's not work. Is there any issue on this?

And also, they will design 3 output transformer with LM5180, however some tools(calc sheet, EVM) has only 2 outputs option. So, how to design this?

Regards,

Hello Kotaro-san,

Currently Webench does not support multiple output condition for this device. We will request the concerned product line on designing this on board.

Thanks and Regards,

Kotaro-san,

Take a look at the dual-output design example in the LM5180 dataheet. We also have numerous multi-output reference designs.

The turns ratio of the third secondary winding is chosen based on the output voltage ratios such that Ns1 : Ns2 : Ns3 = Vout1 : Vout2 : Vout3.
