I checked Phase Margin (PM) using LTpowerCAD about LTM4637.
I loaded default solution in LTpowerCAD.
When Iout = 20 A, Phase + 180 deg is enough in all frequency.
When Iout = a few A,
Iout = 数Aの場合、PM > 70 deg
However, Phase + 180 deg < 20 deg @ 2.5 kHz.
Is it stable when Iout = a few A ?
If at crossover frequency, PM>45 deg, the loop is stable.
Thank you for your advise.
I understood that the loop is stable.
