I made this circuit that is just an astable 555 powered by a capacitive dropper with the output connected to the gate of a MAC97A6 triac. The load (a dimmable LED lamp) does flash, but it never fully turns off, how can I solve this? The triac gate voltage and current seem to be fine.
I want to make a capacitive dropper and i have a 203 film capacitor that i will use for it. What will be the voltage drop on it. I tried to use an online calculator but it doesn’t work.
