Does Inductor Ripple-Current Percentage Still Matter in Low-Power Step-Down Converters? (.PDF Download)

    Nov. 23, 2015

    For decades, power-supply designers have set their inductor ripple current to somewhere between 20% and 40% of their power supply’s full rated output current. This is considered a good starting point for selecting the step-down converter’s inductance. However, not all engineers even agree on this specific percentage range...
