An active approach to EMI mitigation: The first DC/DC regulator with an integrated Active EMI Filter

As electronic systems become increasingly dense and interconnected,
electromagnetic interference (EMI) has become an even more critical system
design consideration. While EMI can be managed to meet desired specifications
(eg CISPR-25) with external filters, the increasing size, complexity, and
cost of such filters pose challenges to the system designer. However, if the
power regulator itself offers enhanced EMI mitigation techniques, then the
reliance on external, passive filters is significantly reduced. In this
recorded webinar, we discuss two EMI mitigation technologies integrated into
the LM25149 synchronous buck controller – Active EMI Filter (AEF) and
Dual-Random Spread Spectrum (DRSS).
