Space-Saving Active EMI Filters Mitigate Common-Mode Emissions (Download)
Since power density is a primary measuring stick for high-power applications in challenging form factors, Texas Instruments’ development of standalone active electromagnetic-interference (EMI) filter ICs that reduce the size of chokes by 50%, trim costs, and help designers meet stringent EMI requirements indeed raises eyebrows.
Granted, that’s a significant claim. The singular question, then, is whether TI can back it up?
The answer is yes. Comité International Spécial des Perturbations Radioélectriques (CISPR) standards are the global benchmark for limiting EMI in electrical and electronic devices. The TI active EMI filter (AEF) ICs sense, process, and mitigate EMI by as much as 30 dB, helping engineers meet CISPR 11, CISPR 32, and CISPR 25 EMI requirements.
