Hi Expert,
Here is power flow. POE 12V> TPS2121
we have around 600uF from POE 12V output to TPS2121 input.
Could I know how to calculated inrush current? And where can I check the internal FET SOA of TPS2121.
I * t = C * V
I = inrush current?
t = POE soft started = 6ms
C= 600u F
V=12V
Please help me check and I correct or not. thanks! Expert
Jim
