16 / 28 page ![]() ADP2380 Data Sheet Rev. 0 | Page 16 of 28 For a duty cycle that is larger than 50%, the minimum inductor value is determined by the following equation: L(Minimum) = SW OUT f D V × − × 2 ) 1 ( The inductor peak current is calculated using the following equation: IPEAK = IOUT + 2 L I ∆ The saturation current of the inductor must be larger than the peak inductor current. For the ferrite core inductors with a quick saturation characteristic, the saturation current rating of the inductor must be higher than the current-limit threshold of the switch to prevent the inductor from becoming saturated. The rms current of the inductor can be calculated by 12 2 2 L OUT RMS I I I ∆ + = Shielded ferrite core materials are recommended for low core loss and low EMI.
