Hi Team,
In order to reduce the ripple current, my customer increased the inductance from 1 uH to 2.2 uH. However, we found that the phase voltage becomes unstable after we made this change. Looking at Table 4 in the datasheet, 2.2 uH doesn't seem to be one of the recommended options.
However, I can't think of any reason why a 2.2 uH inductor can't be used. Please find the phase voltage waveform below.
Here's the schematic.
Thanks!
