LinkSwitch_TN Low-Side Buck-Boost – Optocoupler Feedback
I would like to know if anyone has successfully implemented a low-side Buck-Boost
Optocoupler Feedback design based on the LNK306. If so, can you share your schematics

I have implemented the circuit as shown in the attachment.
I am using the LNK306 device.
I cannot get any output and also C1 is blowing once we turn the power off.
Is the LNK306 the correct part for this design?
Is there some mis-wiring?

Change the value of C4 to 0.1 uF
The actual capacitor on the board is 0.1uF
