We have designed 18W TRIAC DIMMABLE DRIVER using LYT7504.
Please find attached design files of it.
It is not working with dimmer (fan regulator) properly.
We tuned R2,C3, R1,R10 and C4 but now working properly with dimmer.
On line supply (230VAC) it is working fine.
But with dimmer it remains off in some range of it. Also it flickers.
Please suggest best solution.
Thanks & Regards,
