FAN5606 Description
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 from the supply during power on.
