FAN5608 Overview
The FAN5608 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. Proprietary internal circuitry continuously monitors the currrent on both strings and automatically adjusts the generated output DC voltage to the lowest minimum value...
