PRODUCTION DATA
The inductor ripple current is filtered by the output capacitor. A higher inductor ripple current means the output capacitor must have a ripple current rating higher than the inductor ripple current. See Table 7-2 for recommended inductor values.
The RMS and peak currents through the inductor can be calculated using Equation 7 and Equation 8. It is important that the inductor is rated to handle these currents.
During transient/short circuit conditions the inductor current can increase up to the current limit of the device so it is safe to choose an inductor with a saturation current higher than the peak current under current limit condition.
