EUP3595 Parallel White-LED Driver

The EUP3595 is a parallel white-LED driver with four matched current outputs. It can supply a total output current of 100mA over an input voltage range of 3.0V to 5.5V. The amount of constant current sourced to the outputs is user selectable using one external sense resistor. EUP3595 typically draws 0.01µA when placed in shutdown, and 180µA when operating in.
