Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, an SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators.

The use of EEE parts in Space missions involves several considerations that are not usual or critical in other industrial fields. Some typical examples of this are outgassing and radiation characteristics. However, another critical aspect that is not always considered is physical space. In Space applications

Engineers are under time and budget pressures to complete their tasks efficiently. Designing a power supply can be a daunting task, especially for those without much experience. One of the most critical components will be magnetic. For a basic non-isolated buck, boost, or SEPIC converters, the power storage inductor must be determined.
