The DC-DC Converters category covers the MPS buck, boost, buck-boost, e-fuse, flyback, PMIC, PoE controllers and MOSFET driver devices. If the topic concerns one of these devices then use this category. The exception would be for an Automotive part (AECQ qualified), there is a specific forum category for Automotive devices. Forum topics include device operation, component selection, converter theory, or other DC/DC questions.
