Are there any PWM LED drivers that source current in a similar way to the PWM outputs on the Arduino?
I need to drive 30 LEDs (10 RGB) on my LED driver boards (which are made, example below), and consist of a high current BJT switching circuit. Therefore I need to drive the base of the transistor with 0 - 5v.
All the IC's I have found are current sink. Any advice would be greatly appreciated!
