LM5143-Q1EVM-2100: EMI filter deisgn

Part Number: LM5143-Q1EVM-2100
Other Parts Discussed in Thread: LM5143-Q1

Hi,

I am using three LM5143-Q1 power supply IC's each operating at a switching frequency of Max-1MHz and Min-440KHz.

In an EVM(refer attachment) of LM5143 an EMI filter has been designed and kept.

On what basis calculations were considered and for our design can we replicate the same EMI toplogy.

Requirement;

Output voltage from filter=24V

Current=10A

Fs-440kHz
