Minimizing the impact of Electromagnetic Interference (EMI) is one of the biggest challenges when designing switch mode power supplies (SMPS). With varying government requirements on EMI and complex design considerations, it can be quite a difficult task to develop a working power supply. The term “black magic” is often used to describe techniques to reduce conducted and radiated EMI which are inherent in all SMPS. The SIMPLE SWITCHER® apps team has released two new app notes to help demystify EMI mitigation and provide easy guidelines to enable you to successfully design your next SMPS. App note 2155 “Layout Tips for EMI Reduction in DC / DC Converters”, explores how the layout of your DC/DC power supply can significantly affect the amount of EMI that it radiates. Several variations of a layout are presented and analyzed to show optimal layout techniques and provide answers to common EMI questions such whether or not to use a shielded inductor. App note 2162 “Simple Success With Conducted EMI From DC-DC Converters” discusses the theory and provides easy to implement mitigation techniques of the conducted portion of EMI generated by a step-down switcher. Get started now with these new app notes and see how SIMPLE SWITCHER is delivering an ease of use experience.
