LM76003-Q1: EMI test result in datasheet

Johnny Guo

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.

Johnny, we worked together offline to figure this out.

Could you please close this thread.
