Low EMI and Noise performance with DC/DC switching regulators

Concepts of Switching Regulator EMI and Noise Mitigation

Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is noise? What is EMI? 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.

Low EMI and Noise performance with DC/DC switching regulators

Achieving low noise and low EMI performance with DC/DC switching regulators

Mitigating switching regulator EMI and noise is seen by engineers as a black art. Mess with the feng shui of the PCB layout too much, and the system may not pass CISPR standards. Because of this, many power designers simply turn to linear regulators as a guaranteed way to avoid the headache of reducing emissions.

Low EMI and Noise performance with DC/DC switching regulators

EMI and Noise Mitigation Techniques in Practice

Now that we understand the sources of EMI and noise in switching regulators, and some of the common approaches to mitigating each, let's take a closer look at real-world examples of reducing their effects. In this section we will examine the impacts of various mitigation techniques to help you decide which approach makes the most sense in your design. Techniques covered in this discussion include external component placement, filter options and design, frequency manipulation via spread spectrum or dithering, snubbers, boot resistors, and more.

Over-voltage Protection for Multiplexers

System Level Protection for High-voltage Multiplexers in Muti-channel Data Acquisition Systems

  • In the first module, The architecture of a multi-channel data acquisition system and how a multiplexer can be used to facilitate the implementation. Possible causes of fault condition in a typical data acquisition system are discussed, and how the fault condition can severely impact the normal operation of the system is explained.
  • In the second module, protection schemes that can be implemented to protect the system in fault condition using discrete components are discussed.
