Design Tools
Tools that do the arithmetic for you.
Enter what your rail has to do and get starting values for the external parts. The math is the standard buck design equations, filled in with each part's own datasheet data: reference voltage, switching frequency, limits and recommended values. Verify the result in your application.
Buck Converter Designer
Pick a Magnias buck converter, enter your input voltage, output voltage and load current, and get the recommended feedback resistors, inductor and capacitors, plus the application circuit, an efficiency and thermal estimate, the package 3D model and the PCB land pattern.
OpenCross Reference
Search a competitor part number and find the Magnias equivalent, with package and key specifications side by side.
