Reducing power supply solution size has traditionally come at the expense of reduced efficiency and thermal performance. But with TPSM53604 and its routable lead frame (RLF) QFN packaging, this is no longer the case. See how you can leverage the TPSM53604 in your next design to buck the trend and set a new bar for power module size and performance.
Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is EMI? How is this different from noise? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.
Some systems simply require more attention than others when it comes to EMI. In this section, we will examine some of those specific end applications and provide some helpful hints to reach EMI targets with each.
Comité International Spécial des Perturbations Radioélectriques (CISPR) 25 is the typical starting point for evaluating conducted and radiated emissions in automotive systems. This topic addresses the unique challenges of designing power converters to pass CISPR 25 requirements, including background information on the CISPR 25 standard and test setups. We explain common noise sources in power converters and various techniques to reduce conducted and radiated emissions, including input filter design, frequency selection, mode selection, snubber design, shielding and layout.
