The inductor, or load current, flows alternately from V through Q1 and from ground through Q2. The HIP6303 samples the on-state voltage drop across each Q2 transistor to indicate the inductor current in that channel. The voltage drop is sampled ...

Output Inductor Selection One of the parameters limiting the converter’s response to a load transient is the time required to change the inductor current. Small inductors in a multi-phase converter reduces the response time without significant increases in total ripple ...
