Hello
About the soft start function, How to calculate the maximum value of switch current? I didn't see the 40% or 60% from my test result. I didn't see the third step of the soft start either.
And I increase the output capacitance to 60uF(10uF*6), and the output voltage to 15V, but I didn't see the third step.
And the time for the first and second step is 2048cycles, but the first step is not 2048cycles(1cycle=1/1.2MHz),please see Figure25 in the Datasheet, and also the current in the first step is not 40% the maximum current(current of the third step).
