Part selection for driving 4 LEDs using Arduino

Hi, 

I need to drive 4 LEDs independently using an Arduino. I plan to sequentially & independently turn each LED on and I need to be able to adjust the brightness of each LED. 

Three of the four LEDs run at 20mA nominal drive current, but the fourth runs at 50mA.

Is there a driver that is capable of interfacing with the Arduino 3.3V logic level, that supports dimming (PWM), and also allows independent current drive?

Thanks,


Mark
