Nov 3, 2018 at 20:19 comment added Spehro 'speff' Pefhany That's a design decision. There are much better switchmode controller chips than 555s, UC3842 is a classic, and is very cheap, but there are many others.
Nov 3, 2018 at 19:58 comment added sadegh satari "Hardware-based circuits are less of an issue." I thought of something like 555 but I need more control on switching frequency. I used IR2103 to limit intereference between mosfet/transformer and MCU, and I'll isolate their ground and power via routing and inductors. I can use lightbulb during development, that's an awesome idea, but is a ptc enough for the final product?
