FAN5346 Datasheet (Fairchild Semiconductor)

FAN5346, Series Boost LED Driver

The FAN5346 is an asynchronous constant-current LED driver that drives LEDs in series to ensure equal brightness for all the LEDs.

FAN5346S20X has an output voltage of 20V and can drive up to 5 LEDs in series.

FAN5346S30X has an output voltage of 30V and up to 8 LEDs in series.

Optimized for small f
