Smart Consideration of Inductor Thermal Performance for DC-DC Converter Performance and Reliability

Len Crane, Director of Technical Marketing

The efficiency and the thermal properties of key components have very real implications for the success of any converter design. Switching FETs and inductors are generally the two most considered choices determining size and performance of any converter. Though made of vastly different materials of course, and with dif
