Other Parts Discussed in Thread: UCC28740, PMP11155, UCC28050, UCC28180, TINA-TI, UCC28700
I have to design a AC/DC power supply with specifications as follows: -
Requirements: -
Input - 90 - 230 V AC.
Output - 17.2 V , 1.15 A , 20 Watts.
Constraints: -
Power Factor - above 0.9.
Isolated flyback topology.
So, my questions are :-
1) Can UCC28056 alone would be able to achieve both PFC as well as Flyback topology ?
2) If not then, can I go for UCC28056 ( for PFC ) along with the UCC28740 ( for Flyback topology ) in the same circuit ?
So, just as a reference to the 2nd question, I'm attaching the rough circuit diagram of the converter which will be using the UCC28056 along with the UCC28740. Will this circuit shown in the block diagram be able to achieve my requirements ?
please find the attached jpg file for block diagram below.
