I'm afraid of bothering you again. The problem still exists.
I got your idea. But the COMP voltage is about 1.4V in test. While the Level Shifter and Isen Voltage is about 600mV~820mV, so the PWM will always be low level. The gate will always be high level. It's unreasonable. So the V-I Converter and I-V Converter is not 1:1?
Yellow curve is the Voltage of COMP Pin.
I want to know how the soft-start works. The models online cannot realize startup process. Abhishek Tripathy has told me that. The datasheet doesn't illustrate the soft-start function anywhere.
Thanks.
