I have a doubt while selecting the inductor for a buck converter.
In This app note, in the abstract itself, they mention that this :
This application report gives the formulas to calculate the power stage of a buck converter built with an integrated circuit having a integrated switch and operating in continuous conduction mode.
This not mention anything about the DCM mode. So, does it mean that, if I follow the mentioned steps in the app note, for my Vin, Vout and Iout, I will not enter the DCM mode?
I understand about the DCM mode. But in this case, what care should I take while designing such that my selected inductor does not enter DCM.
Vin = 3.3V
Vout = 1.8V
Iout = 0.4A
Selected Inductor = 22uH
