I am trying to drive a RGB-ledstrip using the following circuit: <http://learn.adafruit.com/rgb-led-strips/usage>

As I am using a Common Cathode led-strip instead of a Common Anode one as used in the above link thus I came up with this 'modified circuit'. Because my experience with FETs was nihil this didn't actually work as I would need at least a voltage => Vcc to saturate the MOSFET.

```
                                   VCC
                                    +
                       STP50N06FI   |
                        N-MOSFET    |
                                 ||-+
                  ___            ||<-
                 |   \_----------||-+
                 |___/              |
             Logic 5V (PWM)         |    Ledstrip
                                    V -> (Common
                                    -    Cathode)
                                    |
                                    |
                                   ===
                                   GND

Is it possible to use a N-channel MOSFET at all for this application? and if so, what do I need to do to make this work (Control the LED-strip brightness with a PWM signal, logic 5v).
