... SW As described in the “Theory of Operation” subsection in “Functional Description”, MIC2164/-2/-3 requires at least 20mV peak-to-peak ripple at the FB pin to make the g amplifier and the error comparator to behavior properly. Also, the output voltage ripple should be in phase with the inductor current. Therefore, the output voltage ripple ...
