Well, the LED strip I use is a black box (from an electrical perspective). It just needs 12V, no external resistors.
So I just hooked it up to 12V via the MOS-FET. The PWM signal from the Arduino (plugged into the MOS-FET) does the job of changing the apparent brightness.
No need for magic chips in this context.
