FAN5606 Datasheet (Fairchild Semiconductor)

FAN5606, Serial LED Driver

The FAN5606 LED driver generates regulated output currents from a battery with input voltage varying between 2.7V to 5V.

An internal NMOS switch drives an external inductor, and a Schottky diode delivers the inductor’s stored energy to the load.

Soft start circuitry prevents excessive current drawn
