Low-SideBuck-Boost on LNK3202
I am trying to make a converter based on LNK3202, but it does not produce the required voltage level. I use the Low-SideBuck-Boost -Optocoupler Feedback topology page 3 AH70. If you replace LNK3202 with LNK3206, everything works as it should.
I use an LTV-816 optocoupler, a US1M diode, a BZV55С3V9 zener diode, a 2200 μH choke.
