**Part Number:**LMR50410-Q1

Hi all,

In datasheet section 9.2.2.5, it mentioned a part of output ripple is "caused by the inductor current ripple charging and discharging the output capacitors", and the following equation is given. I had some trouble understanding the coefficient of 8 in the denominator, what is the meaning and reason to put it here?

Also, in the next part it gave another equation to calculate the output capacitor when large current steps exist.

I can see the 8 on the numerator stands for 8 clock cycles, but what is the point to multiply by 1/2？

One more thing,

are these two equations derived from the Q=C*V=I*t?

Many thanks,

Yuanzhao
