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 digital pulses.

current, short circuit detection, and thermal shutdown
protection. In addition, input under-voltage lockout protection
is triggered if the battery voltage is too low.
The FAN5343 is available in a very low profile, small form
factor 2mm x 2mm x 0.55mm 6-lead UMLP package that is
green and RoHS compliant.
