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).
