Hi Dear,
For your question 1), I would suggest you use the simulation tools. You could download the pspice or Tina models of UCC3813 on its page.
For your questions 2), Iout is the load current (average current)
I have been studying a way to design a 200W DC-DC power supply. The main DC bus range voltage of the system is from 180 to 420 Vdc, and it is the input of the power supply. The output of the power supply is 24Vdc+-2%. The power supply needs to be isolated…
