Reduce conducted emissions with an integrated active EMI filter

Description

June 8, 2021

In this short demo, we can see how enabling the integrated active EMI filter on the LM25149 2.1MHz evaluation board 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.
