Abstract: Electromagnetic interference (EMI) poses a significant challenge in the design of LED drivers, particularly in achieving compliance with electromagnetic compatibility (EMC) standards while maintaining development cost-efficiency. This paper explores a set of cost-effective EMI mitigation strategies, including using single bus architectures for universal voltage compatibility, boost converter frequency selection to avoid third harmonic issues, and jitter modulation to flatten EMI peaks in half-bridge converters. Drawing on real-world design experience, these techniques have successfully reduced EMI, lowered development costs, and accelerated time-to-market. The paper also highlights how these solutions align with broader business strategies, offering scalable, globally compliant designs that support market expansion and profitability.
