Light Detection and Ranging (LiDAR) systems may contain a half dozen or more power supplies, sometimes including Boost, SEPIC, Buck-Boost and Flyback topologies. With so many required voltage rails, there are plenty of opportunities for optimization. Inductors (and transformers) play a key role in virtually every system, but selecting the best inductor for each topology can be a challenge. This application note presents new tools and step-by-step guidance to simplify this process.
Stricter guidelines imposed by version 3 of the IEC standard for harmonic current emissions push designers to embrace power-factor-correction methodologies.
The flyback topology is a versatile, widely used, switched-mode power-supply design with some interesting characteristics that brings performance and BOM advantages to many applications...
