hello K, I am sorry to bother u, and I have something dont understand, about"The DC is switched on and off by a transistor controlled by a power supply controller IC. The chopped DC is fed into a flyback[2] transformer which converts it into low voltage AC. Finally, this AC is converted into DC."
I can see the transformer is not big. the high chopped DC voltage can be seen as the high frequency AC voltage? Is there any design details for how to design the transformer? And for the low AC to low DC part, does this
transformation need another transmorfer?
Thanks, I am all fresh for this...Sorry to bother
