Hi.
What I have:
15V DC source
Variable DC source from 1.80V to 3.33V
What I need:
A basic circuit based on Trasistors/mosFETs to drive the Dimmer of the Monitor LEDs with
Variable DC Output from around 5V to 12V based on the variable DC source.
I've replaced the CCFL lamps of a monitor with led stripes, it is working pretty good, but now I'm trying to use the dimmer signal to regulate the LED intensity.
My electronic skills are not enough to accomplish this only by myself, I was able to dimm the screen using a mosFET or a trasistor and a potentiometer to drive them, but I'm not being able to successfully drive them with the dimmer source.
Any ideas are appreciated.
Best Regards.
