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.
