EUP2794, White LED Driver

The EUP2794 is a low noise, constant frequency charge pump that uses a dual mode load switch (1X) and fractional (1.5X) conversion to maximize efficiency for white LED applications.

The EUP2794 delivers up to 80mA of load current and provides four regulated current sources, each capable of driving u
