Use Ohm's law to deturmine that.I think i can use SMT resistances only. Other components might not be available is that package.
I hope i dont get SMT resistance wattage issue.
So does it have mains and separated extra low voltage (i.e. a low voltage DC supply) on the same circuit board?Sorry i do not have a schematic. Just used three different circuits into one. Its an electronics Fan dimmer i have been trying to make.
One portion is the Zero crossing detection, one is Controller portion and one is Power Triac portion.
I want to reduce the size by atleast 30% of the attached circuit.
Why are you using a flip-flop in the same circuit as a microcontroller? Surely the flip-flop can be removed and replaced with a software solution which doesn't take any PCB space.
Yes, I'd agree, that should also save space.I would rotate the optoisolators and the graetz bridge so the power line does not pass close to the isolated circuit.
