PRODUCTION DATA.
The approximate formula for determining the DCM/CCM boundary is as follows:
The inductor internal to the module is 2.2 μH. This value was chosen as a good balance between low and high input voltage applications. The main parameter affected by the inductor is the amplitude of the inductor ripple current (ΔiL). ΔiL can be calculated with:
where
If the output current IOUT is determined by assuming that IOUT = IL, the higher and lower peak of ΔiL can be determined.
