A LED driver integrated circuit has a voltage input pin, a voltage output pin, a capacitor pin, and a switching circuit connected to the capacitor pin and the voltage output pin. The capacitor pin and the voltage output pin are for a flying capacitor to be connected therebetween, and thus the switching circuit and the flying capacitor establish a charge pump to convert an input voltage received by the voltage input pin into an output voltage at the voltage output pin.
