Other Parts Discussed in Thread: TL431, PMP
Dear Sir / Madam,
I am new to power electronics, currently I am also doing the same circuit PFC + Flyback using UCC28810, I have some queries regarding the circuit connection,
1. There are two VDD tags ( next to C7 and R25 ) in the circuit, do i need to connect each other?
2. Like wise, on the transformer secondary side there also 2 VDC tags ( Next to R100 and D11 ), do I need to connect that also?
3. Subject to availability I have used 1N4148 instead of MMSD914 and 1N4007 instead of USK1K -13, I would like to know is it fine to use these alternatives in this circuit ?
I would be very grateful if some could help me with requested information
