Noise and EMI can be detrimental to sensitive analog signal chain circuitry. For this reason, many engineers automatically default to linear regulators. But, in doing so, they are essentially trading one problem (noise) for another (heat dissipation). In this section we will discuss what types of signal chain loads can be driven directly by a switching regulator to get low noise and EMI without sacrificing efficiency. We will also discuss when a linear regulator is absolutely needed to reach levels of noise not possible with a switcher.
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.
The below introductory section features a video briefly discussing what exactly multi-phase buck regulators are, what applications they're suited for, and some of the challenges associated with implementing them. Additionally, the listed resources dive a little deeper into the topics covered in the video, providing further instruction in the beginning of your multiphase journey.
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.

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.
Control theory is often thought to be difficult to understand and theoretical approaches usually have lots of Mathematics and talk about Loop Gain, complex frequency, H(s), G(s) and so on.
As switching converters have evolved, they have taken on a host of new features to operate more efficiently and quietly. To some, however, all these new features listed on the front page of the datasheet may seem foreign. This training series dives into those features to explain the true benefits of each and help you decide which are necessary for your power supply design. Specifically covered in this series are the buck converter topics of:
