Training: The benefits of an integrated active EMI filter
[ Ссылка ]

In this short demo, we can see how enabling the integrated active EMI filter
on the LM25149 2.1MHz evaluation board [1] leads to a 30-dB reduction in
low-frequency conducted emissions. The lower EMI allows for the use of
smaller passive filtering components, thus shrinking overall power supply
size and BOM cost.
