Designing a low-EMI power supply

As electronic systems become increasingly dense and interconnected, reducing the effects of electromagnetic interference (EMI) is becoming an increasingly critical system design consideration. EMI can no longer be an afterthought, as it can cause significant setbacks late in the design phase that cost both time and money. TI offers multiple features and technologies to mitigate EMI in all of the frequency bands of interest. Our devices and technologies can help designers not only improve filter size and cost but also reduce design time and complexity. To help you design a more efficient power supply that meets EMI requirements, start here with our comprehensive training series where we first provide the fundamentals of EMI and then dive deeper into the specific IC and package innovations, design tips regarding external component selection and layout and conclude with application-specific EMI topics.
