I want to design Flyback converter with 200-370VDC input, and 2 outputs, each 3.3V/0.5A. Pi Expert magically provided entire schematic for me. I wondered if there exist any resource that I can use to justify calculations made by the software to select some values and set some parameters. I am specifically interested to know how is duty cycle set, and how is output capacitor and inductor value selected.
In general, my goal is to be able to document my design by explaining why is each component selected.
Any help/direction appreciated.
