One of the major considerations in power systems design is selection of magnetics, specifically, transformers that can support the required current, frequency, and size objectives. Planar magnetics are a low-profile option for many systems where SWaP (size, weight and performance) is a concern. These components use magnetics and packaging with a flat profile, involving windings that effectively stack on each other while wrapping around a large cross-sectional area. This provides very strong coupling to the magnetics core, which keeps magnetic flux confined within the body of the component package.
