PRODUCTION DATA
The inductor is selected to meet the CCM-DCM boundary power requirement, PO(BDRY). In most applications, PO(BDRY) is set to be 1/3 of the maximum output power, PO(MAX). The inductor value is calculated for typical input voltage, VIN(TYP), and output voltage, VO(TYP). From Equation 18, the inductor L is calculated to be:
L ≥ 19.5 μH
The value of L = 22 μH is selected for this application.
Ensure that the inductor saturation current rating is greater than 1.2 × IL(PK) found from Equation 20:
IL(PK) = 3.9 A
