The main parameter for the inductor selection is the inductor value and then the saturation current of the inductor. To calculate the maximum inductor current under static load conditions, Equation 4 is given.
TI recommends choosing the saturation current for the inductor 20% to 30% higher than the IL,MAX, out of Equation 4. A higher inductor value is also useful to lower ripple current but increases the transient response time as well. The following inductors are recommended to be used in designs.
