PRODUCTION DATA.
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 3 is given.
where
TI recommends choosing the saturation current for the inductor 20% to 30% higher than the IL,MAX, out of Equation 3. A higher inductor value is also useful to lower ripple current but increases the transient response time as well.
