Design Tools
Tools that do the arithmetic for you.
Enter what your rail has to do and get real component values, taken from the part's own datasheet — not a generic formula.
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.
