LM76003-Q1: EMI test result in datasheet

Part Number: LM76003-Q1

Hi, team,

I have some questions about LM76003-Q1 EMI test result in datasheet.

1. In below figure, CFLT=4*2.2uF and LFLT=1uH, could you supply the test filter circuit?

2. There is only 400kHz test result, could you supply the EMI test result with 2~2.1MHz Fsw?

Thanks.

Johnny

  • The schematic is spelled out right there Jonhny. In the input path is an L-C filter, with the respective L and C(s) listed.'

    Contact me directly for CISPR 25 Class 5 at 2M results.

    Based on this data, conducted cannot be passed with simple LC as is the case for 400k.
