• What must be checked when increasing the L value of an inductor in a recommended circuit?
    • When the inductance value is increased, if the inductor is of the same size, the rated current may be smaller, and therefore it must be confirmed that the rated current is sufficient. Where operation is concerned, the load transient response performance is worsened, and so voltage fluctuations during load fluctuations must be checked. Also, there are ICs for which a change in inductance value causes a change in frequency characteristics. The frequency characteristics of voltage-mode control ICs in particular must be checked, to confirm that the output voltage is stable with respect to load current transients. For current-mode ICs, when the inductance range is specified, if an inductor in this range is not selected, operation instability may occur.
