  • What should I pay attention to when determining the value of the input capacitor of a step-down DC/DC converter?
    • In essence, the recommended components listed on the data sheet for each IC and their values should be used as reference. Moreover, depending on the DC voltage applied to a capacitor, the effective capacitance of the capacitor is different, and so the characteristic curve provided by the manufacturer indicating the relationship between DC voltage and capacitance should be referenced to select a capacitor for which an effective capacitance equal to that of the recommended component can be ensured. At the same time, recommendations for grade and other parameters should be observed.
