The pieces of a converter you work out before anything else, in the browser. Every result has its own URL, so you can bookmark it or send it to whoever is reviewing the design.
Buck inductor calculator
Minimum inductance for continuous or discontinuous conduction, with the peak and RMS currents and the duty cycle that follow from it.
BuckMagneticsCCM/DCM
Open calculatorInput filter calculator
Size a buck converter's input filter to an attenuation target, then check it against the Middlebrook and GMPM stability criteria before it destabilises the loop.
