FAN5610 - Fairchild Semiconductor

FAN5610 LED Driver

The FAN5610 generates matched current source drives for a maximum of four LEDs. Since each LED current source has its own self-regulating loop, precise current matching is maintained even if there is a substantial forward voltage spread among the LEDs. LED pre-selection therefore is not required. In order to minimize voltage drop, and maximize efficiency, the.
