This is the circuit I have as follows:
Because the output noise is out of limits 120mV(P-P), which is 140mV. I added a capacitor and resistor to parallel with D2. The noise level reduce to 80mV. That is what I want. It is good enough for this level.
But this transient level is high. I want to know which factor causes this problem. My output is as follows:
Also, what suggestion do you want to give me, for example, you can tell me output capacitor C6 or inductor L1 changed? Thank you,
