Dear sir,
I am new bee in electronics. [basically computer guy]
I need to resolve following scenario :
Using 3.3V DC supply [which can provide me PWM signals],i need to make dimming the LEDs [which is operated through AC Line 240V].
I have searched following IC :
But i dont know how to use it...
please help me to resolve this issue.
:)
This chip doesn't provide isolation. I'd think twice about using it if you are not familiar with electronics design.
The chip provides a 7.5v output which presumably you could use to power up PWM circuitry, but I don't know if I would trust bringing the PWM control to the outside world due to a lack of isolation.
If you are just experimenting, why not get a surplus 48vdc switcher, then use a DC/DC to drive the LEDs.
If you are trying to develop a product to sell on the open market, I think this is over your head.
