Hi Genius Folks!
In reference to the TPS23758-EVM, I'm making a board that pretty much follows the design.
I'm curious about how to understand the operation of Q1 (what is the role, and how do all those diodes drive the gate?)
I looked for Primary Side Control Flyback info, but usually I mostly only see D8+RC Snubber as part of the secondary side. But all that other fancy Mosfet/diode gate stuff is new to me. (Can't mentally figure out the direction of current flow/stages of operation)
Is there a similar design I could read into to understand this architecture better?
Thanks a bunch!
