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 w…

PWM Led drivers which source current?

Circuit follows the device's data sheet, except for C11.
