Hi. My name is Roman. I case you want to use transformerless power supply and don’t want to use MOC or something similar, I assume that pcb will have a small size. Or not? Please describe your requirements regarding MOC and transformerless power supply more detailed. Best regards, Roman.

Hi I'm interested in your project. For your requirements I think that we can use an opamp to achieve the control of the triac. The problem controlling this kind of components is the level of voltage needed to their activation. Usually the optocouplers (MOCxxxx and others) are the preferred choice due this components provide an isolation between Digital and analogic circuits. I would like why is the reason to avoid the optocouplers to give you the best proposal. Regards

I know how to do that but minimum you have to use a usb charger to feed the 5V circuit. Tranformerless is very difficult to make.
