Filtering, bypass, and post-regulation are the three primary ways to reduce power-supply noise, but there are some less-used techniques. One is to use a battery to power your circuitry. Batteries are a very low noise power source compared to switching or even linear converters.
Overall, it is not exclusively a function of the control chip but rather the workings of the circuit as a whole. In general, there are three methods of addressing power-supply noise and mitigating ripple. We can utilize a filter to remove noise from a power supply similar to how a filter can remove noise from a signal.
This article focuses on three ways that buck power modules can help with noise reduction: removing parasitics through an integrated module design, mitigating undesired beat frequency and inaccuracies with frequency synchronization, and lowering the input ripple current and output voltage ripple through phase interleaving.
Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design injects back into its input, your first noise problem is getting the noise low enough in your outputs.
To lower the noise of a power rail to a load (R L), you can make an L-C low-pass filter. (Courtesy of Wikimedia) The problem with adding LC circuits is that they have a natural resonant frequency. Thus, it may make your supply unstable or produce unacceptable ringing after transient load changes.
There are three common ways to deal with this noise, that often help with ripple as well: You can use a filter to remove noise from a power supply just like you use filters to remove noise from a signal. Indeed, you can consider the output capacitors part of a filter that reacts against the output impedance of the power-supply circuit.
