Hi there,
I am learning TI slua086 , p7-8 talks about three parameters to consider on diode selection in flyback. I have some questions to consult.
(1) Quote page8 "The peak repetitive forward current is equal to the reflected primary peak current. An MBR2535CTL" . I think when the diode conducting, primay side mosfet is OFF and there should be no primary current, therefore where the "reflected primary peak current" comes from? I am confused.
(2) some notes said Trr (reverse recovery time) is also important for flyback didoe, but it seems not mentioned in diode section of thi paper. Would TI has any advice ?
Thank you!
