Hi,

 

We can see quite big inrush around 3~4A at inductor current on the datasheet(Rev.D) Figure 31. of ADP1613, under the condition of Css=100nF, as shown in below enclosed by red.

Could you please let me know how to prevent above inrush at the inductor ? As well, if you provide more explain why the inrush occurs, it would be very much appreciated.

 

Best Regards,
