Design tools for DC/DC converters

Frederik Dostal, Analog Devices

For many years, engineers have used calculation tools to optimize a switch mode power supply design. In the early years, power supply engineers would program their own tools or use spreadsheets they generated themselves with the required formulas underlying a certain power supply topology. While this helped tr
