Hi ADI Expert
I have seen some inrush current issue on LTC3789 when I connect Iosense+- to Vout, (which stated in the datasheet when no output current sense is required)
as you can see in the below pic1
the Vout rose rapidly to around 4V in a very short time that cause the high Iin inrush current
pic1
however, if I connected Iosense+- to INTVCC (see pic2)
the inrush current was completely off and the Vout was rising smoothly
pic2
May I know the detail reason for the bad Ith control?
Tks
