Other Parts Discussed in Thread: TINA-TI
I simulated with TPS62125 to check the difference between input current with input cap and without input cap in the Tina-ti.
I removed input cap to check input current without input cap, and it is below pictures.
Input cap is used for removing the input current ripple,
I want to know why the input current simulation graph are same?
And, how the input current ripple affected to the IC and system?
