Need help on replacing a diode with as mosfet to realise synchronous rectification

[nesrine12]

I have a schematic with an ac dc converter flyback topology using the vipergan100 that deliver 100W as output power. i want to replace the secondary schottky diode with a mosfet to realise synchronous rectification but i don't know how to do this. the schematic is attached. Could any one help me?

Hi,

same here :

https://community.st.com/t5/power-management/seeking-advice-on-replacing-srk1001-synchronous-rectification/td-p/652987

Why not use the sync rect controller SRK1001 , if you want sync rect ?

here:

about 1 $  -- is this the problem ?
