... Inductor Value I MAX(LOAD) Increase Increase Decrease Decrease © 2007 Fairchild Semiconductor Corporation FAN5350 Rev. 1.0.5 The increased RMS current produces higher losses through the R inductor ESR. Increasing the inductor value produces lower RMS currents, but degrades transient response. For a given physical inductor size, increased inductance usually results in an inductor with lower saturation current ...
