WebI'm designing a step-down buck converter and I'm a little bit worried about ripple current which flows through the output capacitors. In my research on the internet I found that ripple current is given by Vrms_output/ESR. If Ι have 3.5A maximum output current and I want transient responce this mean, 0A to 3.5A = 3.5A ripple current. Webin the data sheet. In this case, use the recommended value and calculate the inductor current ripple I(L1)(PP) which is a rearrangement of Equation 6: (8) The maximum inductor current I(L1)M is the sum of the average component and the half of the peak-to-peak inductor current ripple and is as well the maximum switch current shown in Equation 3.
