Part Number: LM25149-Q1EVM-2100 Tool/software: Hi team,
I used Bode100 to test frequency response of EVM. Vin=18V, 8A-resistive load, and the phase starts from -10° and reach 80° at cross frequency, which is only 29kHz.
Could you help explain…

Hi Darius,
It should only affect the conducted EMI. Can you try shorting out the the input pi EMI filter and try again? It might also be more noticeable if you try different frequencies or a lower quality inductor.
Thanks,
Andrew
