LM5145: LM5145 EVM the inductor core loss

Xing He

Part Number: LM5145

Hi Team，

Can you provide some the materials about CMLS136E-3R3MS（the inductor used in LM5145EVM）that can help to calculate its core loss?

Best Regards

Xing,

We do not characterize core losses, it depend in the internals of the inductor like the core shape and the material

You will have to contact the inductor manufacturer for help with this.

Wurth's Red Expert has online loss calculation https://www.we-online.com/redexpert/

Coilcraft's power Inductor selector will also calculate losses https://www.coilcraft.com/apps/power_tools/power/

Hope this helps,
