Peak transient current calculation

Question asked by pradeep.p on Jul 21, 2017

Hi All,

I have an small confusion on Target impedance calculation for Decoupling.

As per my understanding peak transient current is = 0.5* maximum current,( Ex: Imax= 1A current, then peak transient current = 0.5A).


But most of experts suggesting to consider 1.5* maximum current, Hence peak transient current will be 1.5 A for given 1A maximum current.


Hence i have confusion that which one to follow!!! in Ztarget calculation.


So please if anybody give proper justification on above topic , It will be great help
