but can yew tell meh the formation of pulsating dc using 555 timer ic?
Thanks Alex, I got what I need. I am using the NA555P ic for high power LEDs.
They are 9.8 watts each!
use a transistor, you can fry the 555
the 555 can only switch 200ma of current
Yes, I am using a power mosfet or a DC-DC converter.
