LM2794 - Current Regulated Switched Capacitor LED Supply
The LM2794/95 is a fractional CMOS charge-pump that provides four regulated current sources.
It accepts an input voltage range from 2.7V to 5.5V and maintains a constant current determined by an external sense resistor.
The LM2794/5 delivers up to 80mA of load current to accommodate four White LEDs.
