LM5180-Q1: EMI Plot

Colin Chen

Part Number: LM5180-Q1

Dear Experts

I noticed that the EMI Plot in the chip data sheet only provides data from 150 KHz to 108 MHz. The customer wants to view the data from 108 MHz to 245 MHz. Could you please let me know if this part of the data can be provided? Thank you.

Hello Colin,

Could you please tell which data you require, since Conducted EMI is calculated till 108 MHz.

Please refer An overview of conducted EMI specifications for power supplies for upper limit data as per CISPR 25 standards.

Thanks,

Hareesh.

Hi Hareesh,

Does this mean there is no data available for the frequency band of 108MHz to 245MHz? The customer is looking for data from this specific frequency band. Thank you

Hello Colin,

For Conducted Emissions, as per CISPR-25 standard 108 MHz is the max frequency to test conducted emissions. Above this frequency, there will be radiated emissions. Are you referring to RE data?

Please refer to EVM user guide for this data: LM5180-Q1 Single-Output EVM User's Guide (Rev. D)

Thanks,

Hareesh.
