Hello ，
You may keep R1=20ohm to slow down turning off speed of Q3. Try adding FB or small resistor between VOUT and LED ANODE. Adding small cap on LED anode to GND.
Do you mean LM3409 got damaged if changing C8 to 22uF cap? What do you mean an inductor…
Thank you for your reply, I added some experiments again. and I have some more information to offer you.
I feel like the situation is a little bit like the pulse-by-pulse Current Limit.
The following figure shows the comparison of GHX-GND and PWM waveform…

Part Number: TPS2H000-Q1 您好！
手册中的三个电流参数不理解么参数的含义，麻烦解答下！
Nominal dc load current：不理解此参数含义？
Internal current limit：CL管脚接地的时候，配置的电流限制为1A~1.6A，超过1.6A一定会过载保护，关断输出，是这么理解吗？1A~1.6A是只的两个通到加起来，还是一个通道？
Current limit during thermal shutdown：短路时候电流限制，CL设置的时候是60%设置的限流值…
1. Transient protection is missing. We recommend using TVS diode at the input and Schottky diode at the output to help against transients which are generated in events like hot-plug or short circuit and can cross the absolute maximum of the device resulting…
