FAN5343 Datasheet (Fairchild Semiconductor) - 6-LED Series Boost LED Driver

FAN5343, 6-LED Series Boost LED Driver

The FAN5343 is an asynchronous constant-current LED driver capable of efficiently delivering up to 500mW to a string of six (6) LEDs in series.

Optimized for small form factor applications, the 1.2MHz fixed switching frequency allows the use of small chip inductors and capacitors.

The FAN5343 uses a
