FAN5343 Description

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 single-wire digital control interface to program the brightness levels of the LEDs in 32 linear steps by applying...
