What are points to be noted when determining the capacitance of the output capacitor of a step-down DC/DC converter?
- Basically, the recommended components and their values listed on the data sheet for the IC should be taken as reference. Moreover, depending on the DC voltage applied to the capacitor, the effective capacitance of the capacitor will be different, and so the characteristic curve provided by the manufacturer indicating the relationship between DC voltage and capacitance should be considered to select a capacitor that can ensure an effective capacitance equal to that of the recommended component. At the same time, components should conform to grades and other parameters.
