Hi,
I'm projecting a buck converter with LM16030, and there are four main capacitors that must be
used in this project, and the LM16030 datasheet indicates that all of them must be ceramic capacitors.
We know that capacitance of MLCC varies with bias DC voltage and derating can reach up to
50% in some cases. A example is the graph bellow of a 10uF/50V MLCC:
I must take this reduction into account for all capacitances needed by LM16030 (input capacitance,
output capacitance, boot capacitance and soft start capacitance) and I must use capacitances that are
twice the capacitance calculated for example?
Thanks in advance.
Geraldo Gomes.
