Hello everyone, how should I implement softstart feature to my circuit based on the diagram below? Where V(n006) and I(R6) are the output voltage and current. Thank you for the help in advance.

Hi,

the most straight forward way would be to ramp up your reference voltage V2.

Hello sir, thank you for the response I had tried your method but the inductor current did not change much. Wanted to ask whether there is any other way to reduce the inductor current during start-up? The Figure of the updated version is shown below.
