Hi, TI support team.
In experiment 2,I want to calculate buck input current ripple.
How can choose from these two formulas? I don't know how to judge high and low capacitance.
If define High capacitance as J12 SH(Cin=4.7//4.7//4.7//4.7) and Low as J12 OP(Cin=4.7uF), these formulas seems to be wrong.
And could you please tell me whether formulas(6) is correct or not? Because i think that if Iout is high it seems that input ripple is too high and this regulator may not be worked properly.
Thanks for your support!
