Basic Calculation of a Buck Converter's Power Stage (Rev. B)
www.ti.comselected IC with an inductor with higher inductance if it is still in the recommended range. A higher inductance reduces the ripple current and therefore increases the maximum output current with the selected IC. If the calculated value is above the maximum output current of the application, the maximum switch current in the system is ...

www.thompsonrd.comInductance calculation references necessarily start with Maxwell’s seminal work [1], first published in 1873. Maxwell worked out some interesting inductance problems, including finding the mutual inductance between circular coaxial filaments [1, pp. 339], and finding the size and shape of a coil which maximizes inductance for a given length of
