LM2792 Current Regulated Switched Capacitor LED Driver

The LM2792 is a CMOS charge-pump voltage doubler and regulator that provides two regulated current sources. They are designed to drive two white (or blue) LEDs with matched currents (within ± 0.3%) to produce balanced light sources for display backlights. The LM2792 accepts an input voltage range fr.
