Flyback switching power supply 100~240Vac to 12V 2A, external MOS discrete solution, the chip uses OB2263 or its alternative model

Overview

There are several versions of this power supply, some with built-in MOS and some discrete. I still don’t know how to add a Bom. If you need it, ask me for it.
But I still don’t recommend friends with little hardware experience to copy it casually. After all, high-voltage electricity is still dangerous. If you want to learn, you can ask me for materials. The materials are paid. Providing, not for profit, but the money needed to recover the cost, after all, no one owes anyone.

IR2118 driver has no output
I recently wanted to use a MOS tube to make a heating control. I used an IR2118 driver and was afraid that the power supply would be turned on all the time and the bootstrap circuit would not start, s
What version of IAR does MSP430FR4133 use?
I use IAR6.4 to connect FET430UIF, but can't download the program. FET430UIF has no problem, the program can be compiled but can't be downloaded. It's over with a beep.
